Solar Storm Hits Earth’s Magnetic Field

March 17, 2015By
A G4 (Severe) geomagnetic storm was observed today at 07/1358 UTC (09:58 am EDT). This is the response to a pair of CMEs observed leaving the Sun on 15 March. Shown here is a model depiction of where the aurora is likely visible. Storm conditions are forecast to persist for the next several hours before beginning to wane down towards the end of the UT day.

A G4 (severe) geomagnetic storm is now taking place, the most powerful solar storm of the current solar cycle, reports Discovery.com. Initially triggered by the impact of a coronal mass ejection (CME) hitting our planet’s magnetosphere, a relatively mild geomagnetic storm erupted at around 04:30 UT (12:30 a.m. EDT), but it has since become a severe G4-class geomagnetic storm. Bright auroras were sighted... read more
