Who are India and Pakistan blaming for Delhi, Islamabad blasts?

A day after a bomb blast in Pakistan’s capital, Islamabad, and two days after a similar explosion in India’s capital, New Delhi, tensions in South Asia have heightened. A blame game has intensified between the neighbours who are still reeling from a brief but intense conflict just six months ago.

Here is more about what happened in Islamabad and Delhi, and what Pakistani and Indian officials are saying about the attacks.

What happened in Delhi?

At 6:52pm (13:22 GMT) on Monday, a powerful explosion tore through Delhi, in a densely populated area near the Red Fort Metro Station. At least 13 people were killed and more than 20 people were wounded.

“A slow-moving vehicle stopped at a red light. An explosion happened in that vehicle, and due to the explosion, nearby vehicles were also damaged,” Delhi Police Commissioner Satish Golcha told reporters.

Who has India blamed for it?

While India has not officially blamed anyone, Delhi Police have invoked India’s primary “counterterrorism” law, the Unlawful Activities (Prevention) Act, or UAPA, of 1967.

Police detained the original owner of the vehicle in which the explosion took place. The owner was identified as Mohammad Salman in the city of Gurugram in Haryana state on Delhi’s outskirts. Salman had purchased the vehicle in 2013.

Investigators revealed that Salman sold the vehicle to a man in New Delhi, who later resold it. The man who Salman sold the vehicle to has also been arrested. Despite the sales, the car remained registered in Salman’s name and bore a Haryana number plate, according to local media reports.

During a scheduled trip to the Bhutanese capital Thimpu, India’s Prime Minister Narendra Modi said: “Today, I have come to Bhutan with a very heavy heart. The horrific incident that happened in Delhi last evening has deeply disturbed everyone.”

Modi added: “Our agencies will get to the very bottom of this conspiracy. The conspirators behind this will not be spared. All those responsible will be brought to justice.”

Indian Defence Minister Rajnath Singh also said that investigative agencies are conducting a “swift and thorough” inquiry into the blast.

But despite these statements, Indian leaders and security officials have so far not formally named any individual or group as responsible for the explosion.

How has Pakistan responded to India?

New Delhi has also, so far, not accused Pakistan of being behind the attack.

But Pakistani officials have said that they expect India to blame Pakistan for the attack in Delhi.

While speaking to local media, Pakistani Defence Minister Khawaja Asif said, referring to the attack in Delhi: “I won’t be surprised if in the next few hours or tomorrow India blames us for this.”

What happened in Islamabad?

Less than 24 hours after the attack in Delhi, around 12:30pm (07:30 GMT) on Tuesday, an explosion took place at the entrance of the District Judicial Complex on Srinagar Highway in Islamabad.

Pakistani Interior Minister Mohsin Naqvi said to reporters that a “suicide bomber” detonated explosives near a police vehicle outside the gates of the court.

Naqvi added that the perpetrator tried to “enter the court premises but, failing to do so, targeted a police vehicle.”

The minister said that at least 12 people were killed in the attack in Islamabad and more than 30 were wounded, with at least five in critical condition.

The Jamaa-ul-Ahrar, which is a splinter faction of the Pakistan Taliban (Tehreek-e-Taliban Pakistan or TTP) armed group, has claimed responsibility for the attack. But the TTP, which ideologically aligns with the Afghan Taliban, has denied its involvement in the attack.

Pakistani President Asif Ali Zardari said that he “strongly condemned the suicide blast”.

Who has Pakistan blamed for it?

Pakistani PM Shehbaz Sharif has blamed “Indian proxies” for the attack on Islamabad, without providing evidence.

In a statement, Sharif said: “Terrorist attacks on unarmed citizens of Pakistan by India’s terrorist proxies are condemnable.”

A day before the Islamabad attack, a car packed with explosives crashed into the campus entrance in district capital Wana. Security forces report that at least 300 cadets have been rescued, and operations to free the rest are still under way. Sharif has also blamed India for this attack.

“Both attacks are the worst examples of Indian state terrorism in the region. It is time for the world to condemn such nefarious conspiracies of India,” Sharif said.

Pakistani Defence Minister Khawaja Asif claimed that the attack in Islamabad was planned from Afghanistan, at India’s behest. Relations between Pakistan and Taliban-ruled Afghanistan have been deteriorating for years, hitting a new peak of tension in October following a series of border clashes.

During the clashes, which began in early October, 50 civilians were killed and 447 were injured on the Afghan side of the border, according to the United Nations. At least five people were killed in the Afghan capital, Kabul.

Peace talks between Pakistan and Afghanistan, mediated by Qatar and Turkiye in Istanbul, collapsed on November 7.

At the same time, the relations between India and the Taliban are thawing. Afghanistan’s Foreign Minister Amir Khan Muttaqi visited India in early October, marking the first visit by a top Taliban leader since the group returned to power in 2021.

Earlier this week, Turkish President Recep Tayyip Erdogan announced that Turkiye’s foreign and defence ministers, along with its intelligence chief, will visit Pakistan to discuss Islamabad’s stalled peace talks with Afghanistan.

In a social media post on Tuesday after the suicide attack, Asif had written that Pakistan was “in a state of war”.

How has India responded?

On Tuesday, Randhir Jaiswal, the spokesperson for the Indian Ministry of External Affairs, deemed Pakistan’s allegations that India was behind the attack in Islamabad “baseless and unfounded”.

While responding to media queries, Jaiswal said: “India unequivocally rejects the baseless and unfounded allegations being made by an obviously delirious Pakistani leadership.”

Jaiswal accused Pakistani officials of trying to distract attention from the controversial 27th Amendment to the Constitution of Pakistan that the Sharif government is trying to push through parliament. Opposition parties, activists and sitting judges have criticised the amendment as further consolidating the authority of the country’s already powerful military leadership, and of undermining the Supreme Court by setting up a parallel Federal Constitutional Court. If this amendment becomes law, it would essentially protect the highest-ranking military leaders from criminal prosecution while restructuring the military’s chain of command.

“It is a predictable tactic by Pakistan to concoct false narratives against India in order to deflect the attention of its own public from the ongoing military-inspired constitutional subversion and power grab unfolding within the country,” Jaiswal said.

On Monday, Pakistan’s Senate approved the 27th Amendment. To become law, the amendment needs to secure a two-thirds majority in the National Assembly, the lower house of parliament. The debate around the amendment is ongoing in the National Assembly as of Wednesday.

“The international community is well aware of the reality and will not be misled by Pakistan’s desperate diversionary ploys,” Jaiswal said.

Why have India and Pakistan responded the way they did?

India has exercised more caution compared to Pakistan while ascribing blame, and experts attribute this caution to lessons learned during the conflict in May.

On April 22, armed attackers killed 26 people in Pahalgam, in Indian-administered Kashmir. The attack was claimed by the Resistance Front (TRF), which India alleges is linked to Pakistan-based Lashkar-e-Taiba (LeT) — a claim Islamabad denies.

After this incident, India scaled back diplomatic ties and suspended the Indus Waters Treaty. On May 7, India struck nine sites in Pakistan and Pakistan-administered Kashmir with missiles, which Islamabad said killed dozens of civilians. Over the following three days, the countries engaged in a heated aerial war, using drones and missiles to target each other’s military bases.

A ceasefire was eventually brokered on May 10.

Michael Kugelman, a South Asia analyst, told Al Jazeera that it was “not a surprise that Pakistan has blamed India for these attacks”.

“We’ve seen a pattern in recent years of Pakistan categorically accusing India of sponsoring anti-Pakistan groups, as well as most terrorist attacks inside Pakistan,” Kugelman said. India denies any links with attacks inside Pakistan.

But, Kugelman said, India’s response to the Delhi blast had been complicated by its reaction to the April killings.

“After the India-Pakistan conflict ended in May, Prime Minister Modi essentially announced a new doctrine in which he said that any terrorist attack on Indian soil will be viewed as an act of war, and that the terrorists would not be distinguished from their sponsors,” Kugelman said.

He explained that if India publicly accuses Pakistan right away, under its post-conflict doctrine, it would be compelled to respond forcefully.

New Delhi’s aggressive response in May — without furnishing any proof of Pakistan’s involvement in the Pahalgam attack — “made it difficult for India to sustain support from the international community throughout the conflict, particularly as it continued to wage its strikes in Pakistan,” Kugelman said.

The analyst said he did not expect India to rush to blame Pakistan for the attack unless it finds “smoking gun proof” to publicise.

What do these attacks mean for the region?

Kugelman said that the blasts in Delhi and Islamabad are rare occurrences in these capitals, and they underscore the broad security risks confronting South Asia across a wide stretch of territory.

“There are implications from these attacks for both India and Pakistan, but also Afghanistan, in the sense that Pakistan has blamed Taliban-sponsored militants for the attacks on its soil. Meanwhile, the Taliban have strengthened ties with India.

“You’re looking at a situation that really underscores just how strained the region is now, not just in terms of India-Pakistan relations.”

What’s next?

Kugelman said that what comes next will depend on a variety of factors.

“The immediate factor is what response might there be from each country.”

He predicted that Pakistan is likely to respond against Afghanistan, given Islamabad’s belief that the Taliban is backing militants striking from Afghan soil.

“Talks with the Taliban have not succeeded, and with this attack in Islamabad, I would argue that psychologically it’s very damaging for the civilian and military leadership in Pakistan because Islamabad is a relatively peaceful and safe capital city, highly secure,” Kugelman said.

“These types of blasts are very unusual, so it’s traumatic, it’s embarrassing, and it’s also an intelligence failure.”

Unbeaten Portugal (3-1-0) will seal direct qualification to the FIFA World Cup 2026 if they beat Ireland in their penultimate Group F fixture at the Aviva Stadium.

Armed with a five-point lead, Roberto Martinez’s team are in the box seat to seal a seventh consecutive appearance at football’s global showpiece.

Ireland (1-1-2), for their part, still have a mathematical chance to keep their World Cup aspirations alive by causing a huge upset on Thursday night against an opponent that is fifth in the FIFA world rankings.

They are currently third in the group – but only a point behind second-placed Hungary with two matches still to play. Ireland last qualified for the World Cup in 2006.

Here is all to know about their Group F return clash:

Current Group F standings (two fixtures remaining):

  • Portugal – 10 points (from four matches)
  • Hungary – 5 points (from four matches)
  • Ireland – 4 points (from four matches)
  • Armenia – 3 points (from four matches)

How can Portugal and Ireland still qualify for World Cup in Group F?

Scenario 1: 

Group leaders Portugal require a win against Ireland to ensure direct World Cup qualification into next year’s tournament, which is being held in the United States, Canada and Mexico.

In this scenario, Portugal would have 13 points – an insurmountable lead over the other three teams in the group with just one match remaining.

Scenario 2:

If Portugal were to draw its final two fixtures against Ireland and Armenia, they would also finish top of the Group F standings with 12 points from six matches.

Scenario 3:

If Portugal lose its final two matches against Ireland and Armenia, and Hungary – which currently has five points – wins its final two fixtures against Armenia and Ireland, then Hungary would move top of Group F with 11 points vs Portugal’s 10 points.

If Ireland win their final two games, and Portugal lose their final two games, then the teams would be level on 10 points at the top of the standings with the group winner being decided by goal difference.

All 12 group winners in Europe qualify directly for the World Cup while the runners-up go on to the playoffs for the remaining finals places taking place in March.

What happened in Portugal’s last match against Hungary?

Portugal were on the brink of punching their ticket to the World Cup as they led Hungary 2-1 in stoppage time in Lisbon, knowing a win would confirm first place in Group F.

However, Hungary snatched a late draw when Liverpool’s Dominik Szoboszlai finished from close range in injury time.

What happened the last time Portugal played Ireland?

The teams last played on October 11 in Lisbon.

Portugal’s Ruben Neves scored a stoppage-time goal to snatch a dramatic 1-0 home win in Group F after his teammate Ronaldo had a penalty saved earlier in the match as Ireland threatened to hold the unbeaten hosts to a draw.

Is the 2026 World Cup Ronaldo’s last major international tournament?

Yes. With Portugal on the verge of qualifying for the World Cup, Ronaldo confirmed the tournament in North America will be his swansong on football’s biggest stage.

“Definitely, yes, because I will be 41 years old [at the World Cup],” said Ronaldo, who is also the top scorer in history with 143 international goals.

“I gave everything for football. I’ve been in the game for the last 25 years. I did everything. I have many records in the different scenarios in the clubs and also in the national teams.

“I’m really proud. So let’s enjoy the moment, live the moment.”

Head-to-head

This is only the 18th meeting between the European sides with Portugal winning 10 and Ireland winning four.

Ireland’s last win came in a friendly in 2005, courtesy of Andy O’Brien’s solitary strike in Dublin. There have been four subsequent matches, of which Portugal have won three.

Ireland’s last competitive win against Portugal came in a European Championships qualifier in 1995.

The fixture dates back to 1946 and began with a 3-1 home win for Portugal in a friendly.

Portugal team news

Chelsea winger Pedro Neto has withdrawn from Martinez’s squad after he suffered a groin injury in his side’s 3-0 Premier League victory over Wolves on Saturday. Rafael Leao is the most likely replacement for Neto.

Sporting Lisbon midfielder Pedro Goncalves is also out for a month after an undisclosed injury playing against Santa Clara on the weekend.

“[I’m] out of these next two games and not being able to be present in the World Cup qualifiers. Something I always dreamed of was representing the National Team, and not being able to go hurts. Now it’s time to recover properly, even though I’m not doing what I love the most! Thank you to the team for the effort until the end! We still have a lot to achieve,” Goncalves wrote on social media.

Ronaldo, who has yet to score away to Ireland in four career meetings, will lead the line for Portugal.

Ireland team news

In a big blow to Ireland’s chances, star striker Evan Ferguson is out of the Portugal fixture with an ankle issue and is in doubt for their final World Cup match against Hungary, which may decide who finishes second in Group F.

Manager Heimir Hallgrimsson will also be without three other injured regulars in the squad: Callum O’Dowda (minor knock), Mark Sykes (shin) and Sammie Szmodics (knee).

Ryan Manning and Jayson Molumby are serving one match suspensions.

Predicted starting lineups:

Ireland: Kelleher (goalkeeper); O’Brien, O’Shea, Collins; Coleman, Cullen, Taylor, Johnston; Ebosele, Azaz; Parrott

Portugal: Costa (goalkeeper); Cancelo, Dias, Inacio, Mendes; Fernandes, Vitinha, Neves, Bernardo, Ronaldo, Leao

What the coaches had to say:

Hallgrimsson:

“If Armenia wins or there is a draw, a win in Hungary is enough for us, so that is two of four scenarios for us,” the Ireland manager said.

“If Hungary win, we need at least a draw, but if they win by two or three goals, we will need a draw [against Portugal] and win by maybe three goals away in Hungary.

“We will know what we need in this game against Portugal before we kick off, which is a benefit to us, but it doesn’t change how we start and play the game, but may need to take calculated risks as the game progresses.”

Martinez:

“November is always a difficult stage. Even so, our focus is on qualifying for the World Cup. … We have to improve, especially in the final 20 minutes of games,” Portugal’s manager said.

Did Ukraine’s ‘mafia-linked’ mayor fall victim to a brewing turf war?

Kyiv, Ukraine – Pro-Moscow sympathies, corruption and multimillion-dollar embezzlement, reported ties to Ukrainian, Greek and Italian mobsters and the orchestration of assaults on almost a dozen anticorruption whistleblowers.

That is just an abridged list of the accusations Gennadiy Trukhanov has faced since 2014, when he was elected mayor of Odesa, the nation’s third-largest city and home to its largest seaport and the naval headquarters.

The 60-year-old former military officer and martial arts enthusiast has faced corruption-related arrests in 2018 and investigations in 2023. The latest case involves an “illegal takeover” of government-owned land for real estate development that cost $16.5m, according to Ukraine’s anticorruption prosecutors.

Russian or not?

On October 14, the political drama intensified.

President Volodymyr Zelenskyy decided to strip Trukhanov of Ukrainian citizenship after a scan of the mayor’s allegedly Russian passport was published by Ukrainian intelligence.

Trukhanov denied having Russian citizenship, although a Panama Papers leak years ago appeared to show that he had one – and used it to register offshore companies.

Two days after losing his Ukrainian citizenship, Trukhanov was fired as part of what some observers call a turf war between central and regional authorities caused by the provisions of martial law, conflicting jurisdictions and Kyiv’s push to rein in unruly politicians in front-line regions.

“Trukhanov has long had a serious conflict with political and ideological opponents; they considered him ideologically dangerous and warred with him for years,” Volodymyr Fesenko, head of the Kyiv-based Penta think tank, told Al Jazeera.

Russia has not commented on the incident.

At the time of publishing, Trukhanov had not responded to Al Jazeera’s request for comment.

During a news conference on October 15, he said he never held a Russian passport.

“It’s a moral execution. They just executed me,” he told the journalists.

He is under house arrest and is fighting to restore his citizenship.

On Wednesday, another row with a top official rocked Ukraine as Zelenskyy suspended Herman Haluschenko as justice minister for his presumed involvement in a corruption scandal in the energy industry.

The scandal involved Zelenskyy’s former business partner, who is said to have profited from kickbacks paid by companies that wanted contracts with Energoatom, the state-run monopoly that manages all of Ukraine’s nuclear power stations, according to anticorruption prosecutors and media reports.

Attacks on anticorruption activists

Russian President Vladimir Putin has long wanted to seize Odesa, one of the Soviet era’s most cosmopolitan hubs. It is known as a writer’s city, has a literary museum and is famed for music and an absurdist sense of humour that helps Ukrainians cope with the war.

In 2014, a Moscow-backed separatist uprising threatened the city as clashes killed about 50 people. In 2022, Russian troops tried to take over the city of one million. Today, lethal missiles and drones bring terror to Odesa as the war rages on, while the port’s operations are regularly disrupted.

After the 2014 annexation of Crimea and the 2022 occupation of Ukraine’s ports on the Sea of Azov, the city became a lifeline maritime export route for Ukraine’s grain and steel.

Trukhanov stayed on as mayor after Zelenskyy came to power on an anticorruption ticket in 2019.

Activists in Odesa have claimed Trukhanov allowed corruption and crime to prevail in the years before Zelenskyy’s presidency began.

In 2018, Transparency International Ukraine listed a dozen attacks on activists and “politically exposed persons” in the city as it published a letter signed by civil society representatives calling for action.

In 2019, anticorruption activist Mykhailo Kuzakon told Al Jazeera, “It was Trukhanov’s goons”, as he described how a truck allegedly sped up to run him over near his house in Odesa. He survived the incident, which took place a year earlier, but his colleague’s car was destroyed. During the interview, Kuzakon, the head of the Narodny Rukh (People’s Movement) anticorruption organisation, was wearing a bulletproof vest and had two government-provided bodyguards next to him.

Investigations into the attack on him and other activists did not conclude that Trukhanov was involved after key witnesses refused to testify and evidence went missing.

An excuse for sacking?

Kyiv had been afraid of possible protest rallies that could follow Trukhanov’s sacking, according to Nikolay Mitrokhin, a researcher with Germany’s Bremen University, until a tragic calamity provided a useful excuse.

On October 1, torrential rains flooded Odesa, damaging hundreds of buildings and killing 11, including a child. Critics said the disaster highlighted the Trukhanov administration’s failure to build an effective drainage system despite perennial warnings.

And for the rest of Ukraine, Zelenskyy’s administration “reanimated the story with [Trukhanov’s Russian] passport that is 15 years old and that didn’t stop [the mayor] from effectively managing Odesa during the three-and-a-half years of war,” Mitrokhin told Al Jazeera.

Some Odesans agree.

“Everybody has known for years that Trukhanov had a Russian passport. Everybody has known about his ties to the mob and his hand in every pie,” Oleh, a 43-year-old Odesa native who withheld his last name as he fears for his safety, told Al Jazeera. “He was sacked because only now Zelenskyy is strong enough to get him out of the game.”

In 1998, Italian police described Trukhanov as part of a mafia group suspected of extortion and arms trafficking. Their report said Trukhanov used a Greek passport and was responsible for training gang members in hand-to-hand combat and sniper shooting.

Trukhanov denied the claims but admitted friendship with the people identified as the gang’s leaders.

Others have mixed feelings about Trukhanov’s legacy, crediting him with defending Odesa from Russian forces, but also snubbing the historic centre of the city, founded in 1794.

“Odesa is dirty and shabby. He didn’t take good care of it; [historic] buildings need renovation, trees need a trim,” office manager Zynaida, who moved to Odesa from central Ukraine, told Al Jazeera. She withheld her last name for safety reasons.

Trukhanov will not be replaced by an elected mayor. His 70-year-old deputy, former university professor Ihor Koval, is now acting mayor. Zelenskyy has appointed General Serhiy Lysak as head of Odesa’s military administration.

Lysak is connected to Zelenskyy’s political clan, which mostly consists of figures from the cities of Dnipro and Kryvyi Rih. The group had already tried to gain a foothold in Odesa in 2014, said analyst Mitrokhin.

Ex-boxer boxed in

Trukhanov’s dismissal followed Zelenskyy’s pressure on other powerful heavyweights, including a literal one.

Vitali Klitschko, a former heavyweight boxing champion and mayor of Kyiv since 2014, has been embroiled in a power struggle with Zelenskyy for years.

Klitschko disliked Zelenskyy long before the president – a popular comedian, actor and producer – became a politician.

Zelenskyy’s District 95 comic troupe mocked Klitschko, portraying him in their routines as incoherent.

In real life, Klitschko was a close ally of Zelenskyy’s presidential predecessor and main rival, Petro Poroshenko.

In 2023, Zelenskyy accused Klitschko of failing safety measures after a missile attack killed a nine-year-old girl, her mother and their neighbour as they tried to enter a closed-down bomb shelter.

Their feud grew after Zelenskyy’s appointment of “martial law chief” Tymur Tkachenko as head of Kyiv’s military administration in late 2023.

Tkachenko took over some administrative responsibilities, but critics doubted the necessity of such a figure in the city that sits hundreds of kilometres from the front line. When Russia began its full-scale invasion in February 2022, Russian forces failed to seize Kyiv and withdrew from the region.

The Klitschko and Trukhanov rows could manifest Zelenskyy’s push to quell political opposition “at least” in Ukraine’s south and centre.

“That’s where he sees his electoral base,” analyst Mitrokhin told Al Jazeera.

Solar storms hit Earth: What are they; where can Northern Lights be seen?

Scientists have issued alerts for approaching solar or geomagnetic storms, which are set to hit Earth this week and will produce bright, stunning displays of light known as auroras over parts of the United States, Canada and Europe, while also temporarily disrupting some communications.

On Tuesday, forecasters at the US National Oceanic and Atmospheric Administration (NOAA) said significant geomagnetic disturbances had been recorded in the past few days, specifically in the form of several “coronal mass ejections” (CMEs), which occur when the sun issues bursts of energy. The agency issued a “G4” geomagnetic storm watch signal on a five-level scale, implying that severe storms could be expected.

Some US residents have already shared videos online of northern lights – also known as aurora borealis – which will continue to appear over several US states on Wednesday.

Here’s what we know about the geomagnetic storms and why they occur.

What are solar storms?

Geomagnetic storms occur when storms on the sun trigger disturbances in the Earth’s magnetic field. A solar storm becomes a geomagnetic storm when it reaches the Earth.

Solar storms can occur in two ways. One way is in the form of coronal mass ejections (CMEs), which are sudden swellings of gases on the sun that burst from the sun and travel at more than 1 million mph (1.6 million km/h) towards Earth. Depending on how fast they travel, these can reach the Earth anytime between 15 hours and several days.

Solar storms can also emerge in the form of solar flares, which are sudden eruptions of electromagnetic radiation reaching the Earth from the sun. These travel at the speed of light, reaching Earth in approximately eight minutes, and can last for several minutes or even hours.

Both phenomena happen when magnetic fields on the sun realign. They often, but not always, occur together.

While CMEs can appear through solar telescopes as immense clouds of particles being hurled in a single direction, solar flares appear as bright flashes of light moving in multiple directions. As NASA describes it, think of it as the difference between a cannonball shot in one direction and the flash of a muzzle.

Why are astronomers predicting geomagnetic storms will hit Earth?

The NOAA’s Space Weather Prediction Center said on Tuesday that at least three CMEs would pass over Earth, most likely between Tuesday and Thursday.

In an update early on Wednesday, the agency noted that two of the CMEs, which first erupted on November 9 and 10, had already impacted Earth. They “packed quite a punch”, Shawn Dahl, a scientist with the agency, said in a video update posted on X.

Dahl said the storms were “profoundly more strong than we anticipated” and that while the agency had initially forecasted a G2-level storm, the storms were two levels stronger, at G4.

A third, energetic CME, moving faster than the others, is now set to hit Earth on Wednesday, approximately at midday Eastern Time (17:00 GMT), the space agency said. That one erupted early on November 11 and caused temporary radio blackouts across Africa and Europe, according to Space.com, a leading space exploration publication.

How do geomagnetic storms produce auroras?

When strong bursts of energy erupting from the Sun’s surface as solar flares or CMEs hurtle towards Earth, the highly charged particles they carry collide with gases in the Earth’s upper atmosphere and transfer energy to them, causing the gases to glow and resulting in stunning displays of colourful lights, from emerald greens to intense pinks.

Known as aurora borealis, those displays can be seen from the Northern Hemisphere, hence the term “northern lights”. “Southern lights” or aurora australis are displays which can be seen in the Southern Hemisphere, although far fewer people inhabit the areas from which they are visible. The lights are only visible close to the poles because the Earth’s magnetic fields, which are strongest at the poles, guide the sun’s charged particles towards them.

Light displays have become more common in recent months because the sun is currently at the maximum phase of an 11-year activity cycle.

Every 11 years, the sun’s poles swap places, causing intense magnetic activity. This period, called solar maximum, can last for several months. Scientists speculate that the end of the current cycle began last year and will continue at least through to the end of this year.

In May 2024, the strongest geomagnetic storm in two decades hit Earth and caused dazzling light displays across the US, the United Kingdom and Germany.

Where are the northern lights occurring this week?

Several countries have issued aurora alerts, with some residents already reporting brilliant colours in the sky on Tuesday night.

Brightness and visibility usually depend on what time of day the solar bursts arrive in the Earth’s atmosphere and how they interact with it. Experts recommend leaving brightly-lit areas to see the lights better.

According to NOAA, the lights have already appeared or are likely to appear above several areas in the US, including the states of Illinois (Chicago), Colorado, Massachusetts (Boston), Washington (Seattle), California (San Francisco, Los Angeles), Oregon (Portland), Texas (Dallas), Georgia (Atlanta), North Dakota (Bismarck), New York, Wyoming (Cheyenne), North Carolina (Raleigh) and Iowa.

Other sightings are expected or have been reported in

  • Canada – Expected on Wednesday evening over Montreal, Edmonton, Vancouver, Whitehorse and several other areas, according to The Weather Network.
  • Ireland – Lights have already been seen in Cork, Carlow and Roscommon, according to broadcaster RTE.
  • UK – The Met Office forecast said lights are possible across the northern half of the UK.

Could the storms be harmful?

Not directly to humans, because Earth’s atmosphere protects us from radiation.

However, the bursts of energy could temporarily disrupt communication systems, potentially affecting GPS navigation, radio communications, and satellites, including air traffic control radio and satellites in space. The intense activity could also temporarily disrupt power grids.

On rare occasions, solar eruptions can be damaging. A severe solar storm in September 1859 caused sparks and fires in telegraph stations across Europe and North America. Known as the Carrington Event, those storms were the most intense in recorded history.

In August 1972, powerful geomagnetic events caused widespread electric and communications disruptions in the US and accidentally detonated US naval mines positioned in Vietnam.
