Faint CME seen to the NNE in GOES CCOR-1 and SOHO LASCO C2/C3. The CME is also possibly faintly visible in STEREO A COR2 imagery to the NE. The potential source may be a filament liftoff faintly seen in SDO AIA 304 imagery starting at 2026-10-01T22:01Z around N45E05. No other candidate source eruptions are seen in available EUV imagery.
