Catalog: M2M_CATALOG
Start Time: 2025-02-25T12:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
Activity ID: 2025-02-25T12:38:00-CME-001 (version 2)
Source Location: S15W55
Active Region Number: 13998
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Bright CME first seen in the SW by STEREO A COR2 beginning at 2025-02-25T12:38Z, as well as by SOHO LASCO C2/C3 in later frames. The beginning frames of this event in SOHO LASCO are obscured by a data gap from 25/11:12Z to 25/13:39Z. The source of this CME is an M3.6 flare from AR 3998 (S15W55) as seen in SDO AIA 131. Opening field lines are also visible in SDO AIA 94, 171 and 193, along with an area of dimming seen in SDO AIA 94, 193, 211 and STEREO A EUVI 195.
