Coronal mass ejection — 2026-10-02 19:48 UTC
Faint narrow CME with an anvil-like front seen to the NE in SOHO LASCO C2/C3 and GOES CCOR-1 and fully covered by a large data gap in STEREO A COR2. Its source is likely the notable prominence off/behind the east limb that is best seen in SDO AIA 304/171 and GOES SUVI 304/284. In SUVI it this filament is seen deflecting northwardly.
