Geomagnetic Solar Storm on October 11? What to know about the powerful eruption heading towards Earth
A powerful solar eruption is expected to reach Earth around October 11, potentially causing a G2-level geomagnetic storm. Scientists are monitoring the event for potential impacts on satellite communications and navigation systems.
Why it matters
Geomagnetic storms can disrupt critical infrastructure like power grids and satellite technology, making space weather monitoring essential for global connectivity.
The Sun has released a powerful burst of energy and solar material that could reach Earth around 11 October, potentially triggering a geomagnetic storm.
What is a solar eruption, and why is it significant?
Scientists are monitoring the incoming material for its possible effects on satellites, radio communications and navigation systems, although the extent of any disruption remains uncertain.
According to the US National Oceanic and Atmospheric Administration (NOAA), a geomagnetic storm watch has been issued for 11 October, with a moderate G2-level storm considered likely. The forecast follows two coronal mass ejections (CMEs) released by the Sun on 7 and 8 October.
The 8 October eruption was associated with an M6.7-class solar flare originating from sunspot region 4549. NOAA's Space Weather Prediction Center said the two clouds of solar material could merge while travelling towards Earth, potentially influencing the resulting geomagnetic activity.
