Solar Flare Triggers Severe Geomagnetic Storm Watch for First Time in 20 Years
G5 Storm Forecast for Earth, Raising Concerns of Power Outages and Infrastructure Damage
What You Need to Know About the Potential Impacts
A powerful solar flare has triggered a severe geomagnetic storm watch for the first time in nearly 20 years. The first of several coronal mass ejections (CMEs) reached Earth on Friday, May 10, at 12:37 pm EDT, and was very strong. This event marked the third geomagnetic storm to reach G4 status during the current 11-year solar cycle.
The Space Weather Prediction Center (SWPC) has issued its first G4 watch since 2005, indicating a significant geomagnetic storm is expected to hit Earth within the next 24 to 36 hours. A G5 storm, the highest level on the scale, is possible and could cause widespread power outages, damage to satellites and transformers, and disrupt communications systems.
In 2003, a G5 storm caused power outages in Sweden and damaged transformers in South Africa. Similar effects could occur again if the forecasted storm reaches G5 intensity.
Experts are urging people to be prepared for potential disruptions. This includes having backup power sources, keeping mobile phones charged, and staying informed about the latest updates from SWPC.
