Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-17T09:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-17T09:12:00-CME-001 (version 1)

Source Signature Keyword:
FLR: Flare
Morphology Keyword:
Note: CME first seen to the SE in SOHO LASCO C2 starting at 2025-06-17T09:12Z. CME is also seen to the SE in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. The source of this CME is likely related to some eruptive activity near the SE limb best seen in SDO AIA 304 beginning around 2025-06-17T08:00Z and continuing for a couple of hours. This eruptive activity also includes a C5.5 flare peaking at 2025-06-17T08:13Z.
