Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-17T15:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-17T15:00:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the W in SOHO LASCO C2 starting at 2025-06-17T15:00Z. Also seen to the W in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. There is some northward deflection within the FOV of SOHO LASCO C2. The source of the CME is likely some long duration eruptive activity from beyond the W limb starting around 2025-06-17T13:00Z seen across SDO AIA wavelengths.
