Washington, May 11: The most powerful solar storm in more than two decades struck Earth on Friday, triggering spectacular celestial light shows from Tasmania to Britain -- and threatening possible disruptions to satellites and power grids as it persists into the weekend.

The first of several coronal mass ejections (CMEs) -- expulsions of plasma and magnetic fields from the Sun -- came just after 1600 GMT, according to the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center.

It was later upgraded to an "extreme" geomagnetic storm -- the first since the "Halloween Storms" of October 2003 caused blackouts in Sweden and damaged power infrastructure in South Africa. More CMEs are expected to pummel the planet in the coming days.

Social media lit up with people posting pictures of auroras from northern Europe and Australasia.

"We've just woken the kids to go watch the Northern Lights in the back garden! Clearly visible with the naked eye," Iain Mansfield in Hertford, England, told AFP.

That sense of wonder was shared in Australia's island state of Tasmania.

"Absolutely biblical skies in Tasmania at 4 am this morning. I'm leaving today and knew I could not pass up this opportunity," photographer Sean O' Riordan posted on social media platform X alongside a photo.

Authorities notified satellite operators, airlines, and the power grid to take precautionary steps for potential disruptions caused by changes to Earth's magnetic field.

Elon Musk, whose Starlink satellite internet operator has some 5,000 satellites in low Earth orbit, described the solar storm as the "biggest in a long time."

"Starlink satellites are under a lot of pressure, but holding up so far," Musk posted on his X platform.

Unlike solar flares, which travel at the speed of light and reach Earth in around eight minutes, CMEs travel at a more sedate pace, with officials putting the current average at 800 kilometers (500 miles) per second.

The CMEs emanated from a massive sunspot cluster that is 17 times wider than our planet. The Sun is approaching the peak of an 11-year cycle that brings heightened activity.

'Go outside tonight and look'

Mathew Owens, a professor of space physics at the University of Reading, told AFP that how far the effects would be felt over the planet's northern and southern latitudes would depend on the storm's final strength.

"Go outside tonight and look would be my advice because if you see the aurora, it's quite a spectacular thing," he said. People with eclipse glasses can also look for the sunspot cluster during the day.

In the United States, this could include places such as Northern California and Alabama, officials said.

NOAA's Brent Gordon encouraged the public to try to capture the night sky with phone cameras even if they couldn't see auroras with their naked eyes.

"Just go out your back door and take a picture with the newer cell phones and you'd be amazed at what you see in that picture versus what you see with your eyes."

Spacecraft and pigeons

Fluctuating magnetic fields associated with geomagnetic storms induce currents in long wires, including power lines, which can potentially lead to blackouts. Long pipelines can also become electrified, leading to engineering problems.

Spacecraft are also at risk from high doses of radiation, although the atmosphere prevents this from reaching Earth.

NASA has a dedicated team looking into astronaut safety and can ask astronauts on the International Space Station to move to places within the outpost that are better shielded.

Following one particularly strong flare peak, the US Space Weather Prediction Center said users of high-frequency radio signals "may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth."

Even pigeons and other species that have internal biological compasses could also be affected. Pigeon handlers have noted a reduction in birds coming home during geomagnetic storms, according to NASA's Jet Propulsion Laboratory.

Officials said people should have the normal backup plans in place for power outages, such as having flashlights, batteries, and radios at hand.

The most powerful geomagnetic storm in recorded history, known as the Carrington Event after British astronomer Richard Carrington, occurred in September 1859.

Congress leader Sam Pitroda has stepped down from the post of Chairman of the Indian Overseas Congress and his resignation was accepted by the party. Congress leader Jairam Ramesh took to X and announced that Sam Pitroda had decided to resign from the key post "of his own accord".

Pitroda had been under fire over his controversial remark that Indians in the East resemble the Chinese while those in the South look like Africans.

"We could hold together a country as diverse as India -- where people on East look like Chinese, people on West look like Arab, people on North look like maybe White and people in South look like Africans. It doesn't matter. We are all brothers and sisters," Pitroda said during an interview with The Statesman.

The Congress immediately distanced itself from Pitroda's remarks, terming them "unacceptable".

"The analogies drawn by Mr Sam Pitroda in a podcast to illustrate India's diversity are most unfortunate and unacceptable. The Indian National Congress completely dissociates itself from these analogies," Jairam Ramesh said in a post on X.

The BJP also hit out at the Congress over Pitroda's remarks and termed them "racist and divisive".

Bengaluru: JD(S) leader H D Kumaraswamy has claimed that 25,000 pen drives with videos of women being sexually abused allegedly by his nephew, Lok Sabha election candidate Prajwal Revanna, were distributed before polls, and accused Chief Minister Siddaramaiah and his deputy D K Shivakumar of a conspiracy.

The former chief minister also sought to discredit the Special Investigation Team (SIT) formed by the Congress government on April 28 to probe the charges against Prajwal of sexually abusing several women after videos allegedly involving him started making the rounds on social media.

"It is not a Special Investigation Team but 'Siddaramaiah Investigation Team' and 'Shivakumar Investigation Team'," the JD(S) second-in-command, who is the son of party supremo and former prime minister H D Deve Gowda, said.

MLA H D Revanna and his son and Hassan MP Prajwal have been booked for allegedly molesting their cook. In another case, Revanna has been booked and arrested for allegedly kidnapping a woman who was allegedly sexually assaulted by Prajwal. A case of rape has also been registered against Prajwal.

Addressing a press conference here, Kumaraswamy said the pen drives were circulated by police officers who were "threatened to do it".

“It (pen drive carrying videos) was released in Bengaluru Rural constituency (where the Congress candidate in the Lok Sabha elections is D K Suresh, who is the brother of Shivakumar). This was an April 21 development. On April 22, Poornachandra, our polling agent, gave a complaint to the District Deputy Commissioner, who is the Returning Officer,” the JD(S) leader said.

“Poornachandra received a message at 8 pm on April 21 asking people to 'follow a WhatsApp channel to see Prajwal Revanna’s sleaze video'. There was a message on this WhatsApp channel, 'Countdown for the release of Prajwal’s sleaze videos'," Kumaraswamy further said.

According to Kumaraswamy, one Naveen Gowda had sent the message about the "countdown".

In his complaint to the Deputy Commissioner and the Superintendent of Police of Hassan district, Poornachandra has named five people including Naveen Gowda, Karthik Gowda (Revanna’s driver), Chethan and Puttaraju alias Putty, he said.

It has been more than a fortnight since the complaint made on April 21 but no action has been taken against these five people, Kumaraswamy said and demanded that they should first be arrested for "mortgaging the modesty" of women in the videos.

Kumaraswamy alleged that 25,000 pen drives were distributed in the entire state, and cited a report in a regional daily to support his claim.

“My question here is why no action was taken. If someone posts something on social media, immediately houses are searched and the person is made to sit in the police station. Why no action was taken against these five people despite a complaint?” he asked.

"Chief Minister Siddaramaiah had confidently said that all the three JD(S) candidates in the Lok Sabha elections will be defeated," Kumaraswamy said, adding, "It raises doubts about the involvement of many people."

On April 25, Karnataka State Commission for Women Chairperson Nagalakshmi Chowdhary wrote to Siddaramaiah demanding an SIT probe into the tapes where Prajwal is allegedly seen sexually abusing several women. The same night, the CM gave his nod and ordered the formation of a SIT, Kumaraswamy said.

“In that letter, Nagalakshmi Chowdhary did not mention the name of Prajwal or Revanna but the chief minister called it ‘Prajwal Revanna’s explicit videos’ in his post on X when he announced the formation of SIT. This shows how the conspiracy was hatched,” the JD(S) leader claimed.

He also alleged that the first complaint "framing" his brother H D Revanna and nephew Prajwal was typed on a computer in Bengaluru and was sent to Holenarasipura, which is represented in the Karnataka Legislative Assembly by Revanna, on April 28.

“It’s not a Special Investigation Team but there are two teams within it – one is ‘Siddaramaiah Investigation Team’ and another one is ‘Shivakumar Investigation Team’,” he charged.

He said the ‘convenor’ of the 'pen drive story', Karthik Gowda should be traced first and brought before the people.

“Going through the conspiracies, one can doubt the intention behind the investigation because more than protecting the women victims, you are limiting the scope of the probe only to defame people,” Kumaraswamy further alleged.

He underlined that he was not trying to protect anyone. “I have said that in this case I will not protect anyone doing wrong. Stringent punishment should be given to the person involved in this crime as per the law of land."
