Big Blast from the Sun

by Nancy Atkinson on April 16, 2012

The CME we reported on earlier today was obviously just a warm up to the latest blast: A beautiful prominence eruption producing a larger CME off the east limb (left side) of the sun on April 16, 2012 at about 17:45 UTC (1:45 pm EDT). The event, which also produced an M1.7-class solar flare, was not Earth-directed, say scientists from the Solar Dynamics Observatory. But SpaceWeather.com says the blast confirms suspicions that a significant active region is rotating onto the Earth-side of the sun.
