Powerful solar storm hits Earth, could disrupt communication and power grids
Washington DC: A powerful solar storm, the most potent in over two decades, has struck Earth, triggering stunning celestial displays from Tasmania to Britain and raising concerns about potential disruptions to satellites and power grids as it persists into the weekend.
The event, characterised by several coronal mass ejections (CMEs), began shortly after 1600 GMT, according to the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center.
Upgraded to an "extreme" geomagnetic storm, this marks the first such event since the "Halloween Storms" of October 2003, which caused blackouts in Sweden and damaged power infrastructure in South Africa. Additional CMEs are anticipated to impact the planet in the days ahead.
Social media platforms buzzed with users sharing images of auroras observed in 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," shared Iain Mansfield, a think tanker in Hertford, Britain.
Photographer Sean O' Riordan captured the phenomenon in Tasmania, posting, "Absolutely biblical skies in Tasmania at 4 am this morning. I'm leaving today and knew I could not pass up this opportunity."
Authorities have alerted satellite operators, airlines, and the power grid to take precautionary measures against potential disruptions due to fluctuations in Earth's magnetic field.
Unlike solar flares, which travel at the speed of light, CMEs move at a slower pace, averaging 800 kilometres (500 miles) per second. These eruptions originated from a massive sunspot cluster approximately 17 times wider than Earth, coinciding with the Sun's nearing peak activity within its 11-year cycle.
Professor Mathew Owens, specialising in space physics at the University of Reading, said that while the effects will primarily impact the planet's northern and southern latitudes, the extent of the impact will hinge on the storm's final intensity.
"Go outside tonight and look, would be my advice because if you see the aurora, it's quite a spectacular thing," Owens added, recommending the use of eclipse glasses for daytime observation of the sunspot cluster.
In the United States, areas such as Northern California and Alabama may witness the effects, according to officials.
NOAA's Brent Gordon encouraged the public to attempt capturing images of the night sky with phone cameras, even if auroras are not visible to the naked eye.
Concerns extend beyond disruptions to communication and power infrastructure. Fluctuating magnetic fields can induce currents in long wires, including power lines, potentially causing blackouts. Moreover, spacecraft are at risk of radiation exposure, though Earth's atmosphere provides protection. Additionally, biological compasses in species like pigeons could be affected.
The Carrington Event of September 1859, the most powerful geomagnetic storm on record, caused widespread disruption to telegraph systems due to excess currents, highlighting the potential risks associated with such solar phenomena.

Devine’s all-round brilliance trumps Nandini’s hat-trick as GG edge DC by 4 runs
Navi Mumbai (PTI): Nandini Sharma’s maiden hat-trick went in vain as Sophie Devine starred with a breathtaking 95 and a superb final over under pressure to steer Gujarat Giants to a thrilling four-run win off the last ball over Delhi Capitals in a Women’s Premier League match here on Sunday.
This was Gujarat Giants' second win on the trot, while DC slipped to their second loss.
Sent in to bat, Giants opener Devine smashed seven fours and eight sixes in her 42-ball knock, adding 94 runs for the opening wicket with Beth Mooney (19) to set the platform.
Skipper Ashleigh Gardner kept the momentum going with a brisk 49 off 26 balls, but Nandini turned the tide with remarkable figures of 5 for 33, including a hat-trick, as Gujarat were bowled out for 209.
Chasing a stiff target, opener Lizelle Lee struck a scintillating 86 off 54 balls, studded with 12 fours and three sixes. She put on 41 runs with Shafali Verma (14) before adding 90 off 55 balls with Laura Wolvaardt (77 off 38) to keep Delhi firmly in the hunt.
Once Lee was dismissed by Kashvee Gautam (1/48) in the 15th over, Rajeshwari Gayakwad removed Chinelle Henry (7) to leave Delhi at 146 for three.
Needing 64 off the last 25 balls, skipper Jemimah Rodrigues (15) joined Wolvaardt as the pair plundered 58 runs in 23 balls to bring the equation down to seven off the final five deliveries.
Devine then returned to the spotlight, dismissing both batters and conceding just two runs in the final over to seal a dramatic win.
Earlier, Devine set the tone early, striking three fours off Chinelle Henry before taking Nandini apart with two fours and a six in the fourth over. She was particularly severe on Sneh Rana, hammering two fours and four successive sixes in an over that yielded 32 runs and powered Gujarat Giants to 80 without loss in the powerplay.
The New Zealander brought up her half-century in just 25 balls before Shree Charani broke the opening stand with a sharp caught-and-bowled effort in the ninth over to remove Mooney. Devine briefly regained control, hitting Charani for three sixes, but fell in the 11th over bowled by Nandini Sharma.
Skipper Ashleigh Gardner kept Gujarat Giants on course with a brisk 49 off 26 balls, smashing four boundaries and three sixes to take the side past the 200-mark.
Jemimah Rodrigues pulled off a fine catch to dismiss Georgia Wareham (3), while Henry removed Gardner and Bharti Fulmali (3).
Nandini then capped a memorable outing by picking up four wickets in the final over, including three off the last three balls, to complete her maiden hat-trick.
