All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-02-27T19:12:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: CME visible to the northeast in SOHO LASCO C2/C3. Not visible in STEREO A COR2 due to a data gap starting at 2025-02-27T15:23Z. The source is a filament eruption, with liftoff starting around 2025-02-27T17:36Z, centered around approximately N20E80 as seen in SDO AIA 304. Moving/opening field lines are also visible in SDO AIA 171/193 and dimming is visible in SDO AIA 193.
