Staccato Series

image195

The Sun produced a series of at least eight coronal mass ejections (CMEs) over a two-day period (Nov. 2-4, 2012). Some of them overlapped each other as the Sun burst some of them into space in a rapid-fire style. The series was taken by the STEREO Ahead spacecraft with its COR2 coronagraph, in which the Sun is blocked out by the black disk (Sun represented by the white circle) so that we can observe activity in the corona. These expanding clouds of charged particles also carry magnetic field into space. The bright object moving from right to left below the Sun is the planet Mercury.
