DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-14T21:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-07-14T21:24:00-CME-001 (version 1)
Note Keyword:
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
SB: Streamer Blowout following CME
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
DFLR: Double ribbon flare
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: Wide CME observed to the W/SW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2, with a more southern and a more western lobe visible in LASCO C2/C3 and CCOR-1 which overlap more in COR2. The source is a slow streamer blowout over the SW limb observed best in GOES SUVI 284 beginning around 2025-07-14T20:51Z, likely triggered by or sympathetic with a nearby filament eruption which created separate CME 2025-07-14T19:38Z. As viewed from STEREO A at 2025-07-14T23:05Z, a long post eruptive arcade spans approximately S45W20 to S25W70 (S45W62 to S25W112 as viewed from Earth, with STEREO A presently at W41.88 longitude) in STEREO A EUVI 195 and 304 following the field line movement.

Only later frames of C3 and COR2A are used due to observed acceleration when including earlier frames of C2/C3 and COR2A. 1: Result 1 (2.0 AU)
