Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-23T23:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-09-23T23:24:00-CME-001 (version 2)
Source Location: S15W52
Active Region Number: 14217
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: Thin CME observed to the SW in SOHO LASCO C2/C3 and GOES CCOR-1. This CME is not observed in STEREO A COR2, but it is a thin CME pointed almost directly at STEREO A (~W47.8 at this time) so it may be obscured by the occulting disk. The source may be a small brightening around S15W52 near AR 14217 beginning around 2025-09-23T22:52Z in GOES SUVI 171/195, with some field line movement extending over the SW limb at this time.
