Severe Solar Storm Hits Earth: Potential for Stunning Auroras and Infrastructure Challenges

A powerful solar storm triggered by a significant flare from the sun has reached "extreme" levels, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). The storm, initiated by a coronal mass ejection (CME), struck Earth around midday on October 10, causing a G4-class geomagnetic storm that could impact power grids, GPS, and radio communications.

NOAA's Space Weather Prediction Group (SWPC) reported that the CME reached Earth at 11:17 a.m. EDT, intensifying by 12:57 p.m. EDT. There’s a possibility that the storm could escalate to G5 (Extreme) levels, affecting areas as far south as Alabama and northern California, where the northern lights may be visible.

The storm poses a particular risk to states like North Carolina and Florida, already grappling with power outages from Hurricanes Helene and Milton. NOAA officials warned that the solar storm could further strain these weakened power grids. This G4 storm watch marks only the second issued by NOAA since 2005, following a similar event earlier this year that produced remarkable aurora displays.

The CME was linked to an X1.8-class solar flare, part of a series of intense solar activity that includes an X9 flare from October 3. As the sun continues to show signs of stormy weather, the effects of this solar event may persist into the coming days.
