Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-27T03:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-10-27T03:12:00-CME-001 (version 3)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME first seen to the NNE by SOHO LASCO C2 beginning at 2025-10-27T03:12Z, as well as by SOHO LASCO C3 in later frames. This event is not visible in STEREO A COR2 due to faintness, nor is it visible in GOES CCOR-1 due to an eclipse period from 2025-10-27T04:00Z to 2025-10-27T-6:00Z. There is no clear source seen for this event as it is likely related to far sided activity from former AR 14246 (approx. N25E160).
