Prediction for CME (2023-04-09T09:48:00-CME-001)

CME Observed Time: 2023-04-09T09:48Z
iSWAS Layout URL:
CME Note: Large bright CME seen to the NW in SOHO LASCO C2, C3, and STEREO A COR2. The source appears to be associated with a filament eruption (best seen in SDO/AIA 304) followed by a large area of dimming (best seen in SDO/AIA 193 and 211) and post-eruptive arcade (SDO/AIA 171). The eruption looks like it could stretch across multiple longitudes (~50 to 90+).
CME was not detected at Earth.
