Prediction for CME (2023-02-25T19:38:00-CME-001)

CME Observed Time: 2023-02-25T19:38Z
iSWAS Layout URL:
CME Note: Bright partial halo CME with a bulk portion predominantly to the West in STEREO A COR2 imagery. No SOHO imagery available during initial entry. Source is a filament eruption and simultaneous M6.3 flare from AR13229. An EUV wave is best seen in GOES/SUVI 284 starting at 2023-02-25T18:54Z. A post-eruptive arcade is present in most SDO/AIA wavelengths following the eruption. Likely CME arrival (shock and sheath) are seen at 2023-02-27T10:15Z, as jump in magnetic field to over 20 nT, accompanied by sharp drop in density and temperature. This signature is being discussed with LASSOS team.
