Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-05T04:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-03-05T04:36:00-CME-001 (version 1)

Note: Faint CME visible to the southeast in SOHO LASCO C2 imagery and possibly faintly to the southwest in STEREO A COR2 imagery. The CME is partially obscured by the pylon in SOHO LASCO C3. The CME is not visible in GOES CCOR-1 imagery due to Earthshine. No likely candidate source eruption is seen in available EUV imagery, and the CME is likely far-sided.
