Activity ID: 2025-03-31T00:00:00-CME-001 (version 1)
Source Location: S15E65
Active Region Number: 14048

FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the southeast in SOHO LASCO C2/C3 imagery. It is not observed in STEREO A COR2 due to a data gap lasting from 2025-03-30T19:09Z to 2025-03-31T03:23Z. The source is likely related to an eruption and M1.5 flare from Active Region 14048 (S15E65) starting around 2025-03-30T23:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. A subsequent opening of field lines is visible near the southeast limb around this time in SDO AIA 171 and 193 imagery.
