Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-27T22:25Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-27T22:25:00-CME-001 (version 1)
Source Location: S20E30
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: CME visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2. The source is a filament eruption centered around S20E30. Filament liftoff starts around 2025-03-27T20:19Z in SDO AIA 304. Dimming is best seen in SDO AIA 193, and opening field lines are best seen in SDO AIA 171/193. The eruption is also visible from the point of view of STEREO A EUV 195/304 imagery. The main bulk of the CME is preceded by a fainter, narrower loop in SOHO LASCO C2 at 2025-03-27T21:36Z that may be associated with an eruption from the same region, around S20E30.
