SMM C/P CME Event
26 March 1989 --- Day of Year (DOY): 085
These four images illustrate the filament eruption that accompanied a coronal mass ejection over the west limb of the sun on March 26, 1989. Solar north points toward the upper left corner in each image.
Event Description
Structured cloud with possible concave-outward shaped cavity at southern edge from 14:50 to ~16:40. Loop/cavity or mound appears at 14:50 containing highly structured, loop-shaped (prominence) core. Southernmost edge of (prominence) core evolves into bright hook shape. Event is superposed on streamer. Streamer is disrupted. Deflections.
