ACB raids 15 govt officials including Mangaluru Smart City Ltd executive engineer

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.

Udupi: Udupi became the second city on the Karnataka coast after Mangaluru to launch water rationing, a senior official said on Tuesday.

Commissioner of the Udupi City Municipal Corporation Rayappa said that the rationing system will come into force from Wednesday and will continue till the water in the reservoir reaches comfortable levels.

The dam built across the Swarna river at a place called Baje, which is the only source of water for Udupi city, recorded 3.25 meters of water as against the top level of 6.30 meters.

The decision of water rationing will be reviewed periodically until the reservoir regains its fullest levels, the official said.

The Mangaluru City Corporation resorted to water rationing on Saturday following declining water levels in the reservoir built across the Nethravati river at Thumbe. 

The Israeli military says it has taken full control of the Rafah crossing, which borders Egypt.

Israeli tanks took over the crossing after advancing during the night following heavy bombardment of residential areas.

The military said the crossing is now disconnected from the Salah a-Din road in eastern Rafah, which was seized before.

Tel Aviv said it would continue the operation in Rafah even after the Palestinian resistance movement Hamas said it had agreed to a proposal on ceasefire in Gaza put forward by Qatari and Egyptian mediators.

Earlier, Israeli military aircraft heavily bombed Rafah accompanied with ground advances shortly after Hamas said it had accepted the ceasefire proposal.

The official Palestinian news agency Wafa and Egyptian media said Israeli military vehicles advanced towards the Palestinian side of the Rafah crossing with Egypt, as well as the Karem Shalom crossing with the Israeli-occupied territories.

A Palestinian security official and an Egyptian authority have told the Associated Press news agency that Israeli tanks have entered Rafah, reaching as close as 200 meters from Rafah’s border crossing with neighboring Egypt.

The Israeli military has said it was conducting “targeted strikes” against Hamas in eastern Rafah.

Israeli prime minister Benjamin Netanyahu's office has also said "Israel is continuing the operation in Rafah to exert military pressure on Hamas" in order to advance the release of captives and what it called "the other objectives of the war."

In the meantime, it described the proposal on ceasefire as "far from Israel's essential demands," but added that it would send negotiators for talks "to exhaust the potential for arriving at an agreement."

The military strikes on Rafah came ahead of talks in Egypt on Tuesday aimed at sealing a truce proposal accepted by Hamas, which was put forward by Qatari and Egyptian mediators. 

According to a copy of the proposal, there will be three phases to ending Israel’s onslaught against Gaza.

The first phase calls for a complete withdrawal of Israeli troops from the Netzarim corridor and the return of displaced Palestinians to their homes. The second phase involves an announcement of a permanent cessation of military operations. In the last phase, there would be a complete end to the blockade of the Gaza Strip. 

In return, Israel would be required to release an unspecified number of Palestinian prisoners, withdraw its troops from certain regions of the Gaza Strip, and allow Palestinians to travel from the south of the coastal sliver to the north.

About 1.5 million Palestinians are sheltering in Rafah, once designated a “safe zone” by the Israeli military. Palestinians are now struggling to evacuate the city, after the Israeli military dropped leaflets ordering them to leave as a large-scale assault on the city is planned.

UN Secretary General Antonio Guterres has said that a ground invasion of Rafah would be “intolerable” and called on Israel and Hamas “to go an extra mile” to reach a truce deal.

“This is an opportunity that cannot be missed, and a ground invasion in Rafah would be intolerable because of its devastating humanitarian consequences, and because of its destabilizing impact in the region,” Guterres told reporters on Monday ahead of a meeting with Italian President Sergio Mattarella in New York.

Jordanian Foreign Minister Ayman Safadi has also warned that Israel is “jeopardizing the deal by bombing Rafah.”
