U.S. NOAA Issues Warning for Severe Geomagnetic Storm

(MENAFN) A dangerous geomagnetic disturbance has prompted urgent warnings from federal space weather monitors following the arrival of energetic solar material near Earth's orbit. The U.S. National Oceanic and Atmospheric Administration (NOAA) cautioned that the severe magnetic storm will persist through Thursday after a significant coronal mass ejection penetrated near-Earth space.

Solar eruptions generated extreme activity Tuesday, producing an X5.1-class solar flare coupled with an ejection of charged particles and magnetic plasma. This coronal mass ejection (CME) has now reached the vicinity of Earth's magnetic field after traveling through interplanetary space.

"We have seen the final CME arrive and are now waiting to see just how much magnetic energy exists within," NOAA said in an alert on Wednesday.

Coronal mass ejections represent violent discharges of solar material and electromagnetic fields that pose hazard to Earth when they interact with the planet's magnetosphere, potentially triggering widespread geomagnetic disturbances, according to NOAA specifications.

Health and infrastructure risks mount
The intensified solar radiation environment generates multifaceted operational threats. Enhanced radiation exposure could elevate biological hazards for personnel aboard spacecraft, as well as flight crews and passengers traveling on polar and near-polar routes at elevated altitudes. Satellite infrastructure faces particular vulnerability to single-event effects—unpredictable malfunctions triggered by energetic particles bombarding satellite electronics.
