Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-07T06:08Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-01-07T06:08:00-CME-001 (version 2)
Source Location: S30E25
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: CME visible to the SE in STEREO A COR2 and the SSE in SOHO LASCO C2/C3 and GOES CCOR-1. The CME may be partially obscured by the pylon in GOES CCOR-1. The likely source is an eruption with dimming seen south of AR 14334, around S30E25, starting around 2026-01-07T03:52Z as best seen in SDO AIA 193. The eruption is also seen from the point of view of STEREO A 195, closer to the southeast limb.
