Note: CME seen to the east in SOHO LASCO C2/C3, STEREO A COR2A, and GOES CCOR-1 coronagraphs. The source of this CME is likely a minor filament eruption occurring near the southeast of Active Region 14316 (S10E30) as seen in SDO AIA 171 and 193 around 2025-12-22T09:15Z. An eruption/lifting is visible along the center filament channel with dimming (193) visible along the east and west flanks of the eruptive site with bright post eruptive arcade activity. The SDO AIA 304 imagery also shows a broad area of brightening around the filament channel after the eruption.
