Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-21T00:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-21T00:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: Faint CME observed to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, not observed in STEREO A COR2 due to a data gap. No direct source for this front is observed, so it may likely be far-sided over the NE limb.
