Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-07T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-07T21:12:00-CME-001 (version 1)
Source Location: N40W30
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
J: Jet
Note: Extremely faint and narrow CME seen to the NW in SOHO LASCO C2 and GOES CCOR-1, and to the NE in STEREO A COR2. Source is a subtle area of opening field lines seen around N40W30 (no AR) in GOES SUVI 284 starting around 2025-10-07T20:36Z. This CME becomes diffuse before reaching the SOHO LASCO C3 field of view.

CME Analysis M2M_CATALOG LE true SWPC_CAT 21.0 43.0 332.0 S 12.0 2025-10-08T06:39Z Best fit measurement of extremely faint leading edge using a few frames of SOHO LASCO C2, STEREO A COR2, and GOES CCOR-1, before the leading edge becomes completely diffuse in all three coronagraphs. The leading edge becomes diffuse before reaching the SOHO LASCO C3 field of view. 1: Result 1 (2.0 AU)
