BR: Brightening
Morphology Keyword:
Note: This CME is visible to the E/SE in SOHO LASCO C2 and C3 imagery. There is no STEREO A COR2 imagery available for this event due to a data gap beginning at 2025-04-03T15:23Z. The source is a filament eruption visible along the SE limb in GOES SUVI 304 near S25E70 starting around 2025-03-04T17:32Z. Additionally moving/opening field lines are visible in GOES SUVI 171, 195, and 284, as well as brightening which is best seen in GOES SUVI 195. There is a data gap in SDO/AIA during the eruption for this event.
