BJP intends to arrest 4 more AAP leaders including me for refusing to join party: Atishi

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: A red alert denoting severe heat wave has been issued for six districts of Karnataka by the Karnataka State Natural Disaster Monitoring Centre (KSNDMC), as temperatures are likely to cross 46 degrees Celsius.

Bagalkote, Belagavi, Dharwad, Gadag, Haveri and Koppal districts will see temperatures ranging from 40 to 46 degrees Celsius between May 1 and May 9, according to KSNDMC.

The monitoring centre also pointed out that when comparing the maximum temperature recorded in Karnataka in the past seven years – between 2017 and 2024 – April 30, 2024 recorded the highest, 45.6 degrees Celsius.

Meanwhile, in a statement released by the India Meteorological Department in Bengaluru, the trough/wind discontinuity from southeast Madhya Pradesh to South Interior Karnataka (SIK), across Vidarbha, Marathawada and North Interior Karnataka (NIK) extending up to 1.5km above mean sea level persists.

But as per IMD, the department issued a severe heat (red) alert only when the actual maximum temperature crosses 47 degrees Celsius.

The maximum temperatures are likely to continue and also be around 40 to 46 degrees Celsius over parts of NIK districts, such as Raichur, Kalaburgi, Yadgir, Bellary and Vijayapura districts till May 6, the natural disaster management centre said on social media platform X.

The remaining NIK districts, most of the SIK districts and Dakshina Kannada district are likely to experience maximum temperature between 40 and 44 degrees Celsius, it added.

Parts of Kodagu, Udupi, Hassan, Shivamogga, Chikkamagaluru and parts of Uttara Kannada districts are likely to experience between 33 and 40 degrees Celsius till May 6, according to the centre.

From May 7, maximum temperatures are likely to come down by 2 to 3 degrees Celsius across the state, according to KSNDMC.

Meanwhile, as per realised rainfall across the state data by KSNDMC, while isolated rains were observed in six districts -- Haveri, Dharwad, Gadag, Vijayapura, Shivamogga and Uttara Kannada -- dry/negligible rains were received in 25 districts, including Bengaluru rural and urban on April 30.

Maximum rainfall of 35mm was recorded at Bhogavi in Haveri district.

As per the cumulative date of rainfall from January 1 to April 30, only coastal Karnataka recorded an excess of 59% rainfall from usual, while the rest of Karnataka had deficit rainfall ranging from 13% to 80%, said a press release by KSNDMC, which compiles the data from telemetric rain gauge locations established by it across the state.

Maharashtra Leader of Opposition Vijay Namdevrao Wadettiwar waded into controversy after he alleged that an RSS-affiliated cop, and not terrorist Ajmal Kasab, killed former state anti-terrorism squad (ATS) chief Hemant Karkare during the 26/11 Mumbai terror attack.

In a video statement released on Saturday, the Congress leader alleged that the bullet that killed IPS officer Hemant Karkare did not come from the gun of Ajmal Kasab or any of the other nine Pakistani terrorists involved in the attacks.

Instead, he claimed it came from the weapon of a police officer allegedly "dedicated to" the Rashtriya Swayamsevak Sangh (RSS).

Wadettiwar also accused Ujjwal Nikam, the special public prosecutor in the case and a BJP Lok Sabha candidate from Mumbai North Central, of suppressing this information, labeling him a "traitor."

He questioned the BJP's decision to nominate Nikam for the Lok Sabha polls, accusing the party of protecting traitors.

“During the probe, key information was out. However, it was suppressed by Ujjwal Nikam, who is a traitor. My question is, why is BJP protecting a traitor and nominating such a person for Lok Sabha polls? By doing this, BJP is protecting traitors," Wadettiwar alleged, Times of India reported.

These allegations drew strong responses from Nikam and Deputy Chief Minister Devendra Fadnavis.

Nikam condemned Wadettiwar's statement as "baseless and irresponsible," expressing pain at the doubts raised over his integrity.

He emphasized the legal steps taken to convict Kasab, calling Wadettiwar's remarks an insult to the victims of the 26/11 attacks.

“What a reckless statement is being made. I am pained by such baseless allegations, raising doubts over my integrity. It clearly reflects the level of electoral politics. I never thought politicians will stoop to such low levels. For political gain? He (Wadettiwar) is insulting not me, but the 166 departed souls and all persons injured in the 26/11 attacks," Nikam said.

He added, “They (Congress) hold Kasab as innocent. Even Pakistan had accepted that Kasab was involved in the conspiracy and in the terror attack on India and was guilty".

He said Indians very well know the legal steps he had taken to ensure Kasab’s conviction.

Nikam said citizens of the nation would on 4 June, the day of results for Lok Sabha polls, give their reply to such allegations, adding he wished not to dignify the “desperate disinformation” with a further response.

Meanwhile, BJP leader and Deputy CM Fadnavis said, “Our alliance is with Nikam, while Congress has joined hands with Kasab".

Shiv Sena spokesperson Kiran Pawaskar said NIA should arrest Wadettiwar and ask him why he was defending Kasab.

Pawaskar criticized the Congress for allegedly supporting terrorists and expressed surprise at the silence of Shiv Sena chief Uddhav Thackeray on the matter.

“From Wadettiwar’s statement, it appears Congress is supporting terrorists who attacked Mumbai. More shocking is the fact that Sena (UBT) chief Uddhav Thackeray has maintained silence over the episode,” he said.
