Coronal Mass Ejection From March 7th To Miss Earth

Coronal Mass Ejection From March 7th To Miss Earth
published: Wednesday, March 11, 2015 17:29 UTC

Region AR 12297 produced an M9 flare (R2-Moderate on NOAA Scales) at 2222 UTC (5:22 PM EST) on March 7th which resulted in an impressive coronal mass ejection (CME).  Forecasters have analyzed and modeled this CME and determined that this event will miss the Earth and is directed east of the Sun-Earth line.
