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.

Mangaluru: The Unicode Consortium has announced the inclusion of Tulu script in its latest version, Unicode 16. This update adds 80 characters to the Unicode Standard, marking a significant milestone for the Tulu-speaking community.

According to officials, the journey to this achievement began in 2001 when a member of the Unicode Consortium helped fix the Kannada script in Unicode and simultaneously advocated for the inclusion of Tulu.

Despite initial misunderstandings with the Tulu Academy in Mangaluru, the groundwork was laid for future developments. Initially, three Tulu experts had worked on the subject, including S A Krishnaiah, a Tulu scholar.

"In 2014, efforts to create a Tulu Wikipedia gained momentum, leading to its launch on August 6, 2016. By 2017, the Tulu Academy recognised the need for Tulu Unicode, forming a committee to finalise the characters with technical guidance. Concurrently, another proposal for the Tilari script was submitted," Krishnaiah said.

After extensive correspondence, the script was officially added to Unicode under the name Tulu-Tigalari. While there are minor differences between the Tulu Academy's list and the finalised Unicode version, most characters have been included. Notably, Tulu digits and some diacritic marks necessary for writing Sanskrit in Tulu script were added, he said.

According to him, the inclusion of the Tulu script in Unicode will have a significant positive impact on digital communication for Tulu speakers, including enhanced digital presence. Tulu speakers can now use their native script across various digital platforms, including social media, websites, and messaging apps, fostering a stronger online presence.

The availability of Tulu in Unicode will facilitate the creation of educational materials, such as textbooks and online courses, in the Tulu script, supporting language learning and literacy, he said.

The development of Unicode-encoded fonts, keyboard software, and converters will streamline the use of Tulu in digital communication, making it easier for users to type and share information in their native script, he said.

Being part of the Unicode Standard gives Tulu global recognition, encouraging more software and application developers to support the script, thereby increasing its usability and visibility, the Tulu scholar said.

Overall, this will empower Tulu speakers to communicate more effectively and confidently in their language, both locally and globally.

It is estimated that over 1.8 million people worldwide speak Tulu. Most Tulu speakers live in the coastal areas of Karnataka and Kerala, India, in regions known as Tulu Nadu. There are also Tulu speakers in the Gulf countries and the United States, he said.

Tulu is a Dravidian language and is related to Kannada, the official language of Karnataka. Tulu has a rich oral tradition, but there isn't much written in the language. Tulu's script is similar to Malayalam and originated from the Grantha script.

A long-drawn fight is ongoing to include Tulu in the Eighth Schedule of the Constitution. The Dravidian University at Kuppam in Andhra Pradesh has a special Tulu chair, he added.

Indian wrestler Vinesh Phogat on Friday joined the Congress ahead of the upcoming Haryana Assembly polls and will be the candidate from Julana. Along with Phogat, Bajrang Punia also joined the party.

Meanwhile, Former Wrestling Federation of India (WFI) chief and BJP leader Brij Bhushan Sharan Singh took a jibe at the wrestlers saying, "God has punished them for cheating."

"Haryana is the crown of India in the field of sports. And they stopped the wrestling activities for almost 2.5 years. Is it not true that Bajrang went to the Asian Games without trials? I want to ask those who are experts in wrestling. I want to ask Vinesh Phogat whether a player can give trials in 2 weight categories in a day? Can the trials be stopped for 5 hours after the weigh-in?... You did not win the wrestling, you went there by cheating. God has punished you for the same, " Brij Bhushan said, as reported by ANI.

Additionally he also called out Congress leader Bhupinder Hooda.

"I am not guilty of disrespecting daughters. If anyone is guilty of disrespecting daughters, it is Bajrang and Vinesh. And the one who wrote the script, Bhupinder Hooda is responsible for that. If they (BJP) will ask me (to campaign in the Haryana polls), I can go. One day Congress will have to regret it...," he said.

Both Phogat and Punia met Congress President Mallikarjun Kharge at his residence before officially joining the party at an event at headquarters in the presence of General Secretary (Organisation) K C Venugopal.

Vinesh Phogat, who defied several odds to make the final of the women’s freestyle 50 kg event of the Paris Olympics, was disqualified after being overweight by a few grams.

Now, Olympians Phogat and Bajrang Punia, who were at the forefront of the wrestlers' protest against former WFI chief and BJP leader Brij Bhushan Sharan Singh last year, entered the political arena on Friday by joining the Congress with a vow of "not being scared or backing off".

Hours after joining the Congress, Punia was appointed as the working chairman of the All India Kisan Congress. It seems unlikely now that he would be fielded in the polls.

The 90-member Haryana Assembly is scheduled to go to polls on October 5 and the counting of votes will be undertaken on October 8.

The Israeli regime has attacked displaced Palestinians in the southern part of the Gaza Strip with US-provided 2,000-pound bombs, killing at least 40 civilians, mostly women and children.

As many as 60 others were injured in the attack that targeted an area previously declared by the Israeli military as a “humanitarian zone” at the al-Mawasi refugee camp in the city of Khan Younis on Tuesday.

The military alleged that it had struck members of the Hamas resistance movement, who were “operating a command and control center” inside the targeted area, a claim that was rejected by the group as a “blatant lie.”

“The resistance has repeatedly confirmed the absence of any of its members among civilian gatherings or the use of such areas for military purposes,” Hamas said.

The bloodletting took place as part of the regime’s ongoing genocidal war on Gaza, which began on October 7 in response to a retaliatory operation staged by the territory’s resistance groups.

So far, close to 41,000 Palestinians have been killed and more than 94,800 others wounded in the brutal military onslaught.

The Tuesday massacre came after the refugee camp witnessed an influx of homeless Palestinians, who had fled there from the death and destruction spree caused by the war elsewhere across the coastal sliver. Between 30,000 and 34,000 people were living upon each square kilometer of the camp at the time of the attack, the United Nations estimates show.

The weapons deployed during the massacre have been identified as American-made MK-84 bombs, which carry 900 pounds of explosives. 

The payload can create a crater about 15 meters wide and over 10 meters deep, besides being capable of causing deadly damage around it within a radius of approximately 73 meters. 

This is not the first time when the regime deploys the ammunition against civilian targets during the war. 

More than 70 Palestinians were killed after it struck the refugee camp with the same bombs in July.

As part of its unbridled military support for the regime, the United States has armed it with as many as 14,000 of the bombs since the onset of the war.

Hamas also called the US “complicit” in such massacres that “are being deliberately carried out without regard for international law, humanitarian law, or resolutions calling for an end to the aggression.”
