SpaceWeather.com | HUGE Solar Prominences erupted from the sun's northwestern limb today - April 13, 2010

OMG! HUGE PROMINENCE: One of the biggest prominences in years erupted from the sun's northwestern limb today. The massive plasma-filled structure rose up and burst during a ~2 hour period around 0900 UT. Mark Townley sends this freeze-frame from his backyard observatory in Brierley Hill, West Midlands, UK:

The eruption hurled a bright coronal mass ejection (CME) into space: SOHO movie:

The cloud is not heading toward Earth, at least not directly. A glancing blow from the outskirts of the CME is possible two to three days from now, but any impact is likely to be mild. The eruption was more photogenic than geoeffective.
