Hijab row: 5 girl students seek transfer certificates from Mangaluru University College

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.

Nearly 80 Air India Express flights were canceled after the cabin crew members went on a "mass sick leave", official sources said on Wednesday.

As many as 79 international and domestic flights were canceled after about 300 senior cabin crew members reported sick at the last minute and switched off their mobile phones.

The Air India Express management is currently trying to reach out to the crew, who are protesting against the new employment term at the Tata Group-owned airline, sources said.

The cabin crew has also alleged that there was a lack of equality in the treatment of the staff after the merger with Tata Group. They claim that some staff members were offered lower job position despite clearing interviews, sources said.

"A section of our cabin crew has reported sick at the last minute, starting last night, resulting in flight delays and cancellations. While we are engaging with the crew to understand the reasons behind these occurrences, our teams are actively addressing this issue to minimise any inconvenience caused to our guests as a result," an Air India Express spokesperson said.

"We sincerely apologise to our guests for this unexpected disruption and emphasise that this situation does not reflect the standard of service we strive to provide," the spokesperson added.

Guests impacted by cancellations will be offered a full refund or complimentary rescheduling to another date, the airline said.

Several passengers took to their social media accounts and complained about the sudden cancellations of their flights. They said that they had "no information" about the cancellations.

Some "very disappointed" passengers on X said that they had reached the airport when they were informed that their flights were canceled.

"We apologise for any inconvenience. Please be informed that your flight has been canceled due to operational reasons," Air India Express said in response to one of the posts on X.

Jerusalem: Israel and India will continue to deepen their bilateral ties and lead to greater prosperity, Foreign Minister Israel Katz said on Tuesday.

Katz was responding to India’s External Affairs Minister S Jaishankar’s message on the occasion of Israel’s 76th Independence Day.

“Thank you for the warm wishes, FM @DrSJaishankar. In celebration of our Independence Day, Israel and India will continue to deepen our ties and lead to greater prosperity,” Katz said in a post on X.

Earlier in the morning, Jaishankar posted on X a 2:03-minute video showcasing the India-Israel relationship through photos of various bilateral meetings between Prime Minister Narendra Modi, himself, and other Indian ministers with Israel Prime Minister Benjamin Netanyahu and other ministers.

“Congratulate FM @Israel_katz and the people of Israel on the occasion of the 76th anniversary of Israel’s Independence. Mazel Tov!,” Jaishankar posted along with the video and repeated the same message in another post in Hebrew.

Meanwhile, President Droupadi Murmu wished her Israeli counterpart Isaac Herzog as she said on X, “I join the people of India in conveying our best wishes to President @Isaac_Herzog, and the people of Israel on the 76th anniversary of Israel’s independence.”

Lok Sabha speaker Om Birla too took to X to post his greetings to his counterpart Amir Ohana, the Speaker of The Knesset: “On the occasion of Israel’s 76th anniversary of independence, I congratulate Speaker of the Knesset @AmirOhana and the people of Israel.”

Both Murmu and Birla also included greetings in Hebrew.

“Thank you, my dear friend @ombirlakota. May the friendship between our nations grow stronger,” Ohana replied to Birla and also added a line in Devnagari script in Hindi, loosely translated as, “Thank you my dear friend Om Birla. May the friendship between our countries be stronger.”
