Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-16T08:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-16T08:23:00-CME-001 (version 2)
Note Keyword:
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
FIL: Filament eruption
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: Bright CME visible to the NW in STEREO A COR2 and GOES CCOR-1 imagery. There is currently a data gap in SOHO LASCO C2/C3 imagery for this event. The source of the CME is a filament on/beyond the NW limb in SDO/AIA 304, GOES SUVI 304, and STEREO A EUVI 304 starting around 2025-06-16T04:15Z. Moving/opening field lines are visible beyond the NW limb in SDO/AIA 171 and 193, as well as in GOES SUVI 284.
