Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-28T15:23Z ( SOHO: LASCO/C3 )
All Detecting Spacecrafts:
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-02-28T15:23:00-CME-001 (version 1)
Source Location: N18W02
Active Region Number: 14006
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
J: Jet
Note: CME first seen in the NE by STEREO A COR2 beginning at 2025-02-28T15:23Z, as well as by SOHO LASCO C3 in later frames. This CME is not visible in SOHO LASCO C2 due to a data gap from 28/14:48Z to 28/16:24Z. The source of this event is a jet-like eruption from Active Region 4006 (N18W02), exhibiting a very strong Northeastern deflection in SDO AIA and GOES SUVI 304.
