Coronal Mass Ejection on April 4th, 2014

The movie on the left shows XRT's observations of a C8.3 flare in Active Region 12027 on April 4th, 2014. When the flare begins, the overlying loops in the upper-left can be seen opening up as plasma streams off in that direction. This material forms a Coronal Mass Ejection (CME), a large parcel of plasma that escapes the Sun. The panel on the right shows the CME farther from the Sun in the LASCO coronagraph instrument (red). A small brightening in the upper-left of the AIA/335 image (blue) corresponds to the flare seen by XRT.
