Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-27T07:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-27T07:09:00-CME-001 (version 1)
Source Location: N25E05
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: CME observed to the NE in STEREO A COR2 and faintly in GOES CCOR-1, not in SOHO LASCO C2/C3 due to a real-time downlink gap. The source is a heavily deflected filament eruption observed well in GOES SUVI 304, from a small filament spanning approx. N16E12 to N25W00 (centered N25E05) at 2026-07-27T03:13Z when it began to slowly lift off, more eruptively past 2026-07-27T05:00Z, clearly deflecting sharply NE in the field-of-view. Also observed field line movement and brightening in GOES SUVI 171 and dimming in GOES SUVI 195.
