Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-05T03:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-03-05T03:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME visible to the west in SOHO LASCO C2. The CME is also faintly visible in SOHO LASCO C3 and STEREO A COR2. The CME is not seen in GOES CCOR-1 due to Earthshine. The source of the CME is likely far-sided and not clearly visible in EUV imagery. STEREO A EUV imagery has a data gap from 2026-03-04T16:35Z to 2026-03-05T03:55Z. The potential source may be seen as a filament that gradually lifts off beyond the east limb in GOES SUVI 304 imagery starting around 2026-03-05T01:32Z. Moving field lines are also visible in SDO AIA 171 in ISWA.
