Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-03T12:23Z ( STEREO A: SECCHI/COR2 )

STEREO A: SECCHI/COR2

Note: This CME is visible to the south/southeast in STEREO A COR2 imagery, and is not seen in SOHO LASCO C2/C3 imagery due to a data gap from ~2025-03-03T11:24Z to 2025-03-03T17:12Z. The source may be related to a large southwest filament eruption spanning S55W15 to S40W60 seen in SDO AIA 304 imagery starting around 2025-03-03T11:28Z. An associated dimming region is visible in SDO AIA 193 around this time centered near ~S60W20. Due to the data gap in SOHO LASCO C2/C3 imagery at this time, it is difficult to confirm with a triangulated measurement if this event is related to the filament eruption.
