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.

MP HC sets up judicial commission to probe water contamination in Indore
Indore (PTI): The Indore bench of Madhya Pradesh High Court on Tuesday set up a commission of inquiry comprising a former HC judge to probe the issue of water contamination in city's Bhagirathpura, saying the matter requires probe by an independent, credible authority and "urgent judicial scrutiny".
It also directed the commission to submit an interim report after four weeks from the date of commencement of proceedings.
A division bench of Justices Vijay Kumar Shukla and Alok Awasthi constituted the commission while hearing several public interest litigations (PILs) filed simultaneously regarding the deaths of several people in Bhagirathpura due to the consumption of contaminated water.
The HC reserved the order after hearing all the parties during the day, and released it late at night.
The state government on Tuesday told the HC that the deaths of 16 people in Indore's Bhagirathpura area was possibly linked to a month-long outbreak of vomiting and diarrhoea caused by contaminated drinking water.
The government presented an audit report of 23 deaths from the current gastroenteritis epidemic in Bhagirathpura before the bench, suggesting that 16 of these fatalities may have been linked to the outbreak of vomiting and diarrhoea caused by contaminated drinking water.
The report, prepared by a committee of five experts from the city's Government Mahatma Gandhi Memorial Medical College, stated that the deaths of four people in Bhagirathpura were unrelated to the outbreak, while no conclusion could be reached regarding the cause of death of three other people in the area.
During the hearing, the high court sought to know from the state government the scientific basis behind its report.
The division bench also expressed surprise at the state government's use of the term "verbal autopsy" in relation to the report, sarcastically stating that it had heard the term for the first time.
The HC expressed concern over the Bhagirathpura case, stating that the situation was "alarming," and noted that cases of people falling ill due to contaminated drinking water have also been reported in Mhow, near Indore.
In its order, the HC said the serious issue concerning contamination of the drinking water supply in Bhagirathpura area allegedly resulted in widespread health hazards to residents, including children and elderly persons.
According to the petitioners and media reports, death toll is about 30 till today, but the report depicts only 16 without any basis or record, it said.
It is averred that sewage mixing, leakage in the pipeline, and failure of civic authorities to maintain potable water standards have led to the outbreak of water-borne diseases. Photographs, medical reports, and complaints submitted to the authorities prima facie indicate a matter requiring urgent judicial scrutiny, the HC said.
"Considering the gravity of the allegation and affecting the right to life under Article 21 of the Constitution of India and the need for an independent fact-finding exercise, the Court is of the opinion that the matter requires investigation by an independent, credible authority," it said.
"Accordingly, we appoint Justice Sushil Kumar Gupta, former judge of the Madhya Pradesh High Court, a one-man commission of inquiry into the issues relating to water contamination in Bhagirathpura, Indore, and its impact on other areas of the city," the HC added.
As per the order, the commission shall inquire into and submit a report on the cause of contamination -- whether the drinking water supplied to Bhagirathpura was contaminated; and the source and nature of contamination (sewage ingress, industrial discharge, pipeline damage etc).
The panel will also probe the number of actual deaths of affected residents on account of contaminated water; find out the nature of disease reported and adequacy of medical response and preventive measures; suggest immediate steps required to ensure safe drinking water as well as long-term infrastructural and monitoring reforms.
It will also identify and fix responsibility upon the officers and officials found prima facie responsible for the Bhagirathpura water contamination incident, and suggest guidelines for compensation to affected residents, particularly vulnerable sections.
The commission shall have powers of a civil court for the purpose of summoning officials and witnesses; calling up records from the government department, hospitals, laboratories and civic bodies; ordering water quality testing through accredited laboratories; conducting spot inspections.
All state authorities involving district administration, Indore Municipal Corporation, public health engineering department and Madhya Pradesh Pollution Control Board shall extend full co-operation and provide records as sought by the commission, it said.
The state government shall provide office space, staff, and logistical support to the commission, it said.
During the hearing in the day, the state government also presented a status report to the court in this matter.
According to reports, a total of 454 patients were admitted to local hospitals during the vomiting and diarrhea outbreak, of whom 441 have been discharged after treatment, and 11 are currently hospitalised.
According to officials, due to a leak in the municipal drinking water pipeline in Bhagirathpura, sewage from a toilet was also mixed in the water.
