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: Karnataka Home Minister G Parameshwara on Sunday said that the Special Investigation Team (SIT), probing into sexual abuse charges against Hassan MP Prajwal Revanna, will not be going abroad to bring him back, and the Interpol will share information about him.

He also cautioned political leaders about making public statements or sharing information in connection with the case, which is sensitive.

The 33-year-old Prajwal Revanna, who is grandson of JD(S) patriarch and former Prime Minister H D Deve Gowda, is facing charges of sexually abusing several women.

The scandal has raised a political storm with the ruling Congress and BJP-JD(S) engaged in a slugfest.

Prajwal Revanna is said to have flown abroad on April 27, a day after the first phase of Lok Sabha polls in Karnataka was held.

He was BJP-JD(S) alliance's joint candidate from Hassan Lok Sabha segment, which went to polls in the first phase.

"No, there is no such option. Blue Corner Notice has been issued and the Interpol will share the information. The respective country in which he is found or identified - they will inform them (Interpol) and then our agencies, the CBI will get to know, and through them we will get to know."

"So far there is no information," Parameshwara said.

He was responding to a question on reports about the SIT team travelling abroad in connection with the case.

Speaking to reporters, he said, "Investigation is going on, not to affect the investigation we don't want to share any information."

Responding to a question on Union Minister Pralhad Joshi's statement alleging conspiracy behind the arrest of BJP leader Devaraje Gowda, for making allegations against Congress leaders in connection with the case, Parameshwara said, "If anyone says anything I cannot react to it. We cannot respond to every public statement. As this is a serious case, we cannot share information until the investigation is completed."

"My request to the public and to our leaders is to be cautious while making statements. If not, based on the statements given by them, we may have to call them for investigation and record their statement under 41 A of CrPC," he added.

Asked whether JD(S) leader H D Kumaraswamy will also be served notice, the Minister said he is a former CM and that he believes that the former has taken this case seriously.

"Before giving any statements on this case or before sharing any information in the public domain, one has to be cautious, and this applies to all," he added.

Mangaluru, May 6: A five-year-old girl from Arendur village of Siddapura taluk of Uttara Kannada district died of Kyasanur Forest Disease (monkey fever) recently.

As her health deteriorated, she was admitted to the KMC Hospital in Mangaluru, where she failed to respond to the treatment and died on Friday night.

It is learned that the KFD is slowly spreading to the newer areas of coastal and malnad areas of Karnataka

According to officials, KFD spreads due to bites of ticks that generally survive on monkeys. This tick bites humans which causes the infection. Humans also contract the disease by coming in contact with cattle bitten by ticks.
