Britain is preparing for its most powerful solar storm in over two decades, with warnings that it could trigger widespread power blackouts and disruption to communication networks.
The British Geological Survey (BGS), headquartered in Keyworth, Nottinghamshire, elevated its geomagnetic forecast to the most severe level on Wednesday, November 12, affecting the afternoon and evening periods.
The government body cautioned that the phenomenon, referred to as a 'cannibal storm', could have a "significant impact" on communication networks, electricity grids and GPS satellite systems.
"Space weather can have a real impact on the lives of people across the planet," said Dr Gemma Richardson, a geomagnetic hazard specialist at BGS.
"BGS records real-time data of geomagnetic conditions, underpinning the national forecast service.", reports Nottinghamshire Live.
"Our data suggests that this event could be one of the biggest storms we've seen in 20 years."
Geomagnetic storms occur when solar activity collides with the Earth's magnetic field, presenting risks to national energy systems.
Latest forecasts indicate a follow-up storm, building upon the initial one, could potentially escalate to G5 status, representing the highest severity rating possible.
The storm is also expected to produce spectacular Northern Lights, known as aurora borealis, visible throughout UK skies, comparable to last year's displays.
As with all forecasts, it remains impossible to determine the storm's exact magnitude, which can journey from the sun to Earth in merely 17 hours, according to BGS. The agency stated: "Based on satellite observations, we anticipate this event will be significant; early indications such as ground measurements of solar energetic particles are some of the largest recorded since 2005."
They added: "Assuming clear, dark skies, there is an increased chance of seeing the aurora borealis from the UK tonight. Observers in Scotland, northern England and Northern Ireland have the best chance if the weather is favourable."
