Sun eruption video
Earlier this morning an active region still over the eastern limb of the Sun erupted and exploded, hurling plasma into space. Getting this side view shows the power and force behind these solar flares and coronal mass ejections. This event was not Earth directed. This video covers approx. 2 hours and 40 minutes from 02:30 through 05:10 UT on May 1, 2013. Credit: NASA SDO
