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.

Bengaluru: In a fresh development in the alleged Hassan sex abuse case, JD(S) MLA H D Revanna, who was accused of sexually harassing his house help, has been booked for kidnapping a victim allegedly sexually assaulted by his son, Hassan MP Prajwal Revanna. The case was filed late Thursday evening at the KR Nagar police station in Mysuru.

The 20-year-old complainant from KR Nagara accused one Sathish Babanna of taking his mother away forcibly and keeping her in an unknown location at the behest of Revanna.

As per the FIR, Revanna has been named as accused 1 while Babanna was accused 2. The duo were booked under IPC Sections 364A (kidnapping for ransom), 365 (kidnapping or abducting with intent secretly and wrongfully to confine a person) and 34 (acts done by several persons in furtherance of common intention).

The complainant claimed that his mother, whose name and age were not revealed, had worked as a help in Revanna’s house and farm in Holenarasipura for six years, quit the job three years ago and returned to KR Nagara. She then worked for daily wages.

“Nearly three to four days before the Lok Sabha election, Sathish Babanna, who is known to us and hailed from our native place, took my mother to Holenarasipura after saying that Bhavani Revanna, the wife of MLA Revanna, had asked for her,” the complainant alleged, adding that Babanna dropped her back on the day of the polls.

Babanna allegedly told the victim’s mother and father to remain silent and evade the police if they came looking for them and to inform him of the developments.

On April 29, at around 9 pm, when the complainant was home, the suspect Babanna arrived, told the complainant’s mother that Revanna had asked for her and took her away on his motorcycle. The complainant claimed that he wasn’t aware of where Babanna took his mother and he had told him that if the police found her, a case would be registered and they would all go to jail.

On May 1, two of the complainant’s relatives called him on the phone and told him that there was a video of his mother being sexually assaulted by Prajwal and that it was a huge case, the FIR noted. He was also informed by his two friends of his "mother's videos being circulated".

When he asked Babanna later that night, he was allegedly told that there was a photo of his mother standing with a stick when Prajwal had quarrelled with someone earlier and an FIR had been registered. Babanna told the complainant that his mother would have to be released on bail, the FIR noted.

“Babanna told me not to speak on the matter on my phone and asked me to talk from a different phone,” he said, seeking action from the police.

The case has been transferred to the Special Investigation Team (SIT) set up to probe the Hassan sex scandal as per the government order.

US riot police have dismantled an anti-war and pro-Palestinian protest camp at the University of California at Los Angeles, a day after it was attacked by pro-Israel supporters.

At least 200 pro-Palestine protesters were arrested during the pre-dawn raid, led by a phalanx of California Highway Patrol officers carrying shields and batons, early on Thursday.

The protesters tried to block the officers' advance by their sheer numbers, shouting "push them back", while hundreds of pro-Palestinian activists who assembled outside the tent city were heard chanting "Shame on you" at the police.

According to estimates of local television station KABC-TV, 300 to 500 protesters were hunkered down inside the camp, while about 2,000 more had gathered outside the barricades in support.

The raid took place about a day after police watched on as pro-Israel groups violently attacked the encampment. Late Tuesday night, masked counter-demonstrators mounted a surprise assault on the camp, using sticks to beat the peaceful activists.

The assault went on for three hours into early Wednesday morning until police intervened and restored order.

The authorities’ slow response drew wide criticism from political leaders, including a spokesperson for California Governor Gavin Newsom who said "limited and delayed campus law enforcement response" to the unrest is "unacceptable."

The Pro-Palestine demonstrations began at Columbia University in New York City on April 17, and have spread across other campuses in the US in a student movement unlike any other this century.

US police arrested about 2,200 people during pro-Palestinian protests at college campuses across the country in recent weeks, the Associated Press reported.

A tally by the news agency recorded at least 56 incidents of arrests at 43 different US colleges or universities since April 18.

The students are calling for an end to Israel’s genocidal war on Gaza and demanding schools divest from companies that support the Israeli regime.

Israel launched the war on Gaza on October 7 after the Palestinian resistance movement Hamas waged the surprise Operation Al-Aqsa Storm against the occupying entity in response to the Israeli regime's decades-long campaign of bloodletting and devastation against Palestinians.

Tel Aviv has also blocked water, food, and electricity to Gaza, plunging the coastal strip into a humanitarian crisis.

Since the start of the offensive, the Israeli regime has killed at least 34,596 Palestinians and injured 77,816 others.
