Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-22T00:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
Activity ID: 2026-06-22T00:38:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
Note: Narrow and faint CME visible to the West in STEREO A COR2 imagery and faintly visible to the NW in SOHO LASCO C2 difference imagery. The source of this CME is not clearly seen due to a data gap prior to the CME start time, but may possibly be associated with eruption activity from the area of old Active Regions 14464 and 14467 beyond the W/SW limb.
