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.

Triangulated measurement of the leading edge between SOHO LASCO C3 and STEREO A COR2, capturing the full width of the eruption with the southern lobe slightly ahead of the western lobe. Only later frames of C3 and COR2A are used due to observed acceleration when including earlier frames of C2/C3 and COR2A. |
