Ukraine war will escalate if West supplies longer-range missiles, warns Russia

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.

A senior UN official says around 800,000 people have been "forced to flee" Rafah in the southern Gaza Strip since the Israeli regime began carrying out ground incursions into the refugee-packed city from various axes.

Philippe Lazzarini, the head of UNRWA, the UN agency for Palestinian refugees, made the remarks in a post on X, former Twitter, on Saturday.

"Nearly half of the population of Rafah or 800,000 people are on the road having been forced to flee since the Israeli forces started the military operation in the area on May 6," he said.

The invasion of the city came amid a genocidal war against Gaza by the regime that has so far claimed the lives of more than 35,300 Palestinians.

Around 1.5 million Palestinians had taken refuge in Rafah prior to the incursions, having fled there from the ravages of the war that began following a retaliatory operation against the occupied territories by Gaza’s resistance groups.

The Gazans, who have now left the city, have fled to "the middle areas and [the southern Gaza city of] Khan Younis, including to destroyed buildings," Lazzarini said.

Al-Mawasi, a 14-square-kilometer town on the coast, as well as the central city of Deir el-Balah, were "crammed" with recently displaced people, he added.

"Every time, they are forced to leave behind the few belongings they have ....Every time, they have to start from scratch, all over again."

The Israeli military has, meanwhile, seized the Rafah crossing in southern Gaza, which borders Egypt and serves as the main point of entry for aid supplies, including fuel, into Palestinian territory.

The move came as part of an all-out siege that the regime has been enforcing against the entire Gaza simultaneously with the war.

Mangaluru: Dakshina Kannada Zilla Panchayat High School in Harekala, popularly known as Padma Shri awardee Harekala Hajabba’s school, is gearing up to inaugurate its first batch of Pre-University (PU) courses starting June 1. 

The government issued an order to elevate the school established by Padma Shri awardee Harekala Hajabba to the status of a PU College a few months ago.

The School Education and Literacy Department (PU Education) has formally sanctioned the upgrade for the school.

CD Jayanna, the deputy director of PU Education, confirmed that all necessary approvals have been obtained from the government to initiate PU classes.

“Hajabba’s school will kick off PU classes for its inaugural batch on June 1. We have appointed a senior lecturer as the interim principal for the PU college. Presently, the school possesses the essential temporary infrastructure to begin the I PU batch. Plans are underway to enhance the infrastructure for the PU college in the future. Currently, the school boasts adequate classrooms and facilities to commence PU classes,” stated Jayanna.

Harekala Hajabba, an orange vendor, personally erected the school in his native village, New Padpu in Harekala, situated approximately 35 km from Mangaluru. For several years, he has tirelessly petitioned the government for the establishment of a PU college.

Expressing his gratitude, Hajabba mentioned that 19 students who recently completed their SSLC examinations are poised to enroll in the new PU college. He added, “We anticipate enrollment from neighboring villages as well. Both the interim principal and the PU education department have been diligently orchestrating the necessary arrangements to initiate classes.” 

He extended his appreciation to the government, local representatives, and officials for their unwavering support.
