Prediction for CME (2023-04-15T12:36:00-CME-001)

CME Observed Time: 2023-04-15T12:36Z
CME Note: Faint CME visible in the N/NE of SOHO LASCO C2/C3 and in the N/NW of STEREO A COR2. The source is a filament eruption seen lifting off in SDO AIA 304 starting around 2023-04-15T10:00Z. Dimming is also observed in SDO AIA 193 and STEREO A EUVI 195. Arrival occurs near 2023-04-19T09:22Z with extended rotations in the By and Bz magnetic field components as observed by ACE/DSCOVR. This might mean a crossing between the nose and the flank (more towards the flank). The plasma signatures are not very straightforward. This can be because the ICME arrives at the back of the SIR or because of the flank crossing. The possible end of the ICME is 2023-04-21T05:14Z.

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.
