Coronal mass ejection — 2026-11-06 10:53 UTC
Narrow CME visible to the west in STEREO A COR2. The CME is not clearly visible in GOES CCOR-1 imagery. SOHO LASCO C2/C3 imagery is not available due to a downlink data gap. The potential source is an eruption seen near the west limb in STEREO A EUV 195/304 located around N20W160 starting around 2026-11-06T03:15Z. The eruption can be seen as an ejecta of material in STEREO A EUV 304. Moving field lines and post-eruption arcades are also visible in STEREO A EUV 195 imagery.
