Catalog: M2M_CATALOG
Start Time: 2026-02-28T07:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-02-28T07:09:00-CME-001 (version 2)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
BR: Brightening
Morphology Keyword:
Note: Narrow, bright CME visible to the N/NE in STEREO A COR2 and GOES CCOR-1 imagery. This CME is not visible in SOHO LASCO C2/C3 due to a data gap. The source of this CME appears to be a filament eruption visible on the Earth-facing disk between N20E10 to N30E40 based on brightening as seen in GOES SUVI 304 and 284 starting around 2026-02-28T06:00Z.
