Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-23T16:15Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
Activity ID: 2026-03-23T16:15:00-CME-001 (version 2)
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 SW only in GOES CCOR-1. SOHO LASCO is in a downlink gap, and the CME may be too faint or directed towards STEREO A COR2. No distinct source for this CME is observed, but based on its direction and recent eruptions it may be an outflow from AR 14392 following significant CMEs 2026-03-22T23:24Z and 2026-03-23T02:36Z.
