On Monday, the Earth experienced a significant solar storm that has the potential to extend the visibility of the northern lights to regions further south than usual, as reported by a US agency. The US National Oceanic and Atmospheric Administration (NOAA) confirmed the occurrence of a level four geomagnetic storm, rated on a scale of five, starting at 1500 GMT on Monday. While these conditions could persist for several hours, NOAA specified that the intensity is not expected to escalate further. According to NOAA, a severe geomagnetic storm could lead to the faint appearance of auroras as far south as Alabama and northern California.
This recent solar storm was triggered by coronal mass ejections (CMEs), which are bursts of particles emanating from the Sun. Upon reaching Earth, these particles interfere with its magnetic field. Eric Lagadec, an astrophysicist at the Cote d’Azur Observatory in France, mentioned the current abundance of auroras and the possibility of observing them until nightfall.
Over the weekend, Nasa astronaut Matthew Dominick shared a stunning photograph of the aurora borealis, captured from the International Space Station where he is currently stationed. While these solar and geomagnetic storms offer captivating sights like the auroras, they can also have adverse effects. These effects include disruptions to high-frequency communications, satellite operations, and potential strain on the electricity grid. To mitigate these consequences, operators of critical infrastructure have been advised to implement precautionary measures, as communicated by NOAA.
In May, the planet encountered the most potent geomagnetic storms recorded in the past two decades. These events led to the illumination of auroras across the night skies of the United States, Europe, and Australia, reaching latitudes typically not associated with such phenomena.
