Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-04-23T12:08Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-04-23T12:08:00-CME-001 (version 2)
Source Location: N10E30
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
J: Jet
Note: This relatively narrow CME is visible to the northeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery and is better seen in COR2A than in other coronagraphs. The source may be related to a dimming region centered near N10E30 observed starting around 2026-04-23T11:30Z.
