Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-21T22:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-07-21T22:00:00-CME-001 (version 2)
Source Location: N25W76
Active Region Number: 14143
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Narrow CME first seen to the NW in SOHO LASCO C2 starting at 2025-07-21T22:00Z. Also seen to the NW in SOHO LASCO C3 and GOES CCOR-1 but is not visible in STEREO A COR2. There appears to be some deflection northward later into its propagation, particularly into the FOV of SOHO LASCO C3. The source of this CME is most likely eruptive activity from AR 14143 nearing the NW limb best seen in GOES SUVI 284 as rising field lines beginning around 2025-07-21T20:20Z. The eruption can also be seen in STEREO A EUVI 195. This is the first CME in a series of successive fronts to the NW that are most likely all from the same source region.
