Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-15T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2026-03-15T22:12:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
J: Jet
Note: Very faint jet with a fuzzy front seen to the NW in SOHO LASCO C2 and in one or two timestamps of C3 running difference imagery. This event is not seen in GOES CCOR-1 or STEREO A COR2 imagery due to data gaps starting at 2026-03-14T23:15Z and 2026-03-14T12:09Z, respectively. No clear source has been found for this CME in EUV imagery.
