Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-27T02:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3

Activity ID: 2025-12-27T02:12:00-CME-001 (version 3)
Source Location: S09E72
Active Region Number: 14325
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: CME observed to the E in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is an M5.1 class flare from AR 14325 (S09E72) observed in SDO AIA 131 which peaked at 2025-12-27T01:50Z, also observed as field line movement and post-eruptive arcades in SDO AIA 171/193/211/304 that appear to deflect NE of the eruption source. This deflection is further corroborated by the triangulation of the CME longitude to around E95-E100 in the CME analysis tool.
