Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-03T11:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-05-03T11:53:00-CME-001 (version 1)
Source Location: N10E55
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines

Morphology Keyword:
Note: CME first seen in the NE by STEREO A COR2 beginning at 2025-05-03T11:53Z, as well as by SOHO LASCO C2/C3 and GOES CCOR in later frames. The source of this event is an eruption seen in SDO AIA 193 and 211 beginning at approximately 2025-05-03T10:39Z centered at approximately N10E55, but exhibiting some Eastern deflection. Dimming can be seen in SDO AIA 211 and post eruptive arcades are visible in SDO AIA 131 and 193.
