Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-01T08:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-03-01T08:00:00-CME-001 (version 1)

Note: CME faintly seen to the SE in SOHO LASCO C2/C3 and STEREO A COR2. The start time is unclear, as the CME is not clearly seen in earlier frames in the coronagraphs. The source is not found in available EUV imagery, and may be far-sided.
