Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-27T09:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-27T09:24:00-CME-001 (version 2)
Source Location: N15E61
Active Region Number: 14100
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Wide CME observed to the northeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is a broad opening of field lines to the northeast centered on disk around N15E61, north of AR 14100 (N08E61), observed best in SDO AIA 171/193 and GOES SUVI 284 beginning slowly around 2025-05-27T07:16Z and faster starting around 2025-05-27T08:06Z. Accompanied by some slight dimming in SDO AIA 193 well north of this central point, spanning a thin arc ~N35E90 to ~N35E40, then down to ~N08E33. This minor increase in brightening is associated with a brief post-eruptive arcade seen from Active Region 14100 and is accompanied by a long-duration post-eruptive brightening from the surrounding area near and around Active Region 14100. Long-duration post-eruptive brightening near and around Active Region 14100 can be seen in SDO AIA 131. Two brief brighter arcades forming at Active Region 14100 resulted in a C4.5 and a C5.0 flare.
