A powerful solar flare erupted from the sun on Tuesday, prompting warnings from NASA about potential blackouts and communication disruptions. 

The solar flare, classified as an X1.2 flare, one of the most severe types, exploded from the sun’s Earth-facing side at around 6pm ET.

‘X-class denotes the most intense flares, while the number provides more information about their strength,’ NASA shared in a release.

The eruption unleashed a burst of ionizing radiation, magnetic energy and heat capable of interfering with technology on Earth.

Dr. Tamitha Skov, who is an independent space weather physicist, noted that the flare had its strongest effect in the western hemisphere. This impacted regions such as the US West Coast, Alaska, eastern Russia, the Asia-Pacific area, and possibly New Zealand.

The flare caused an immediate shortwave radio blackout over the Pacific Ocean, with ham radio enthusiasts in Hawaii experiencing a sudden loss of signals.

NASA, along with other space weather organizations, is keeping a close watch on sunspot region 4114, which is the origin of the flare. Sunspots are areas on the sun’s surface that are cooler than their surroundings.

Sunsport 4114 is expected to remain active in the coming days, and scientists warn that another major flare could erupt as soon as today.

‘Another flare may be in the offing today. Sunspot 4114 is large and unstable, with a “delta-class” magnetic field that harbors energy for strong explosions,’ the team at SpaceWeather.com shared.

A delta-class magnetic field is like a pressure cooker of magnetic energy on the sun, and it is often a warning sign that a big solar flare is to come. 

Dr Tamitha Skov, an independent space weather physicist, said the flare’s impact was strongest in the western hemisphere, affecting areas including the US West Coast, Alaska , eastern Russia , the Asia-Pacific region and potentially New Zealand

 However, it has the potential to cause minor fluctuations in power grids, slight impacts on satellite operations and make the aurora borealis visible at high latitudes. 

In May, experts revealed they conducted an extreme space weather scenario and found Earth may not survive.

They conducted a ‘solar storm emergency drill’, simulating what would happen if a major geomagnetic storm hit our planet.

Results showed power grids failed, blackouts were triggered and communication broke down across the US.

The exercise ran four simulations of geomagnetic storms of different severities.

One scenario included a ‘solar superstorm’, strong enough to cause an ‘internet apocalypse,’ resulting in power grid disruptions across the entire US, with the eastern seaboard experiencing blackouts, which lasted for weeks.

Not only were power grids impacted, but railways and pipelines were also knocked offline, causing mass disruptions of travel and dramatic price increases of gas.

Scientists are now calling for a whole-of-government planning approach, arguing it will be critical for protecting America from cosmic disaster.

That would include deploying more satellites to monitor space weather, enhancing real-time data collection to improve forecasting models and providing earlier warnings.
