Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-09T08:48Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2025-06-09T08:48:00-CME-001 (version 1)

OFL: Moving/Opening field lines

Morphology Keyword:

Note: This CME is visible to the northeast in SOHO LASCO C2/C3 and STEREO A COR2 imagery. This event is not seen in GOES CCOR-1 as it is obscured by the pylon. The source is likely related to an opening of field lines observed over the northeast limb in SDO AIA 171 and 193 imagery starting around 2025-06-09T08:30Z.
