PEA: Post eruption arcade
DIM: Dimming
Morphology Keyword:
Note: This CME is visible to the southeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is likely related to an eruption and dimming centered near S28E05 starting around 2025-07-21T03:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. Post eruptive arcades begin to form around 2025-07-21T04:30Z.
