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

CME Observed Time: 2023-02-25T19:38Z
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.
CME Shock Arrival Time: 2023-02-27T10:15Z

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
