Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-31T14:45Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2026-01-31T14:45:00-CME-001 (version 2)
Source Location: N28W20
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
OS: Other and Shock Candidate
Note: Faint CME with a pointy, dimpled front to the NW in SOHO LASCO C2 and GOES CCOR-1, partially obscured by a pylon in SOHO LASCO C3. The corresponding super faint, messy front is possibly seen to the NE in STEREO A COR2 in a few limited timeframes. The source of this CME could be a very small eruption just E of former AR 14365 (~N28W20), seen in SDO starting at 2026-01-31T13:49Z as minor dimming and small size post-eruptive arcades.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.
