Start Time: 2025-08-11T09:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-08-11T09:53:00-CME-001 (version 3)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the SW in STEREO A COR2, GOES CCOR-1, and SOHO LASCO C2/C3 imagery following a data backfill. There was a data gap in real-time for this CME in SOHO LASCO imagery. There isn't a clear source, however multiple moving/opening field lines are visible along the SW limb in GOES SUVI 284 starting around 2025-08-11T08:30Z.
