Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-07T07:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-07T07:09:00-CME-001 (version 3)
Source Location: S21E46
Active Region Number: 14244
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
PRM: Prominence material (filamentary structures)
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Bright CME first seen to the SE in STEREO A COR2 beginning at 2025-10-07T07:09Z, as well as by GOES CCOR-1 and SOHO LASCO C2/C3 in later frames. The source of this event is a slow erupting filament beginning at approx. 2025-10-07T05:21Z located near AR 14244 (S21E46), although is likely deflected due to its proximity to a large coronal hole. This filament is seen clearly in GOES SUVI and STEREO A EUVI 304, along with field line opening visible in GOES SUVI 284 and STEREO A EUVI 195.
