Prediction for CME (2023-09-22T02:24:00-CME-001)

CME Observed Time: 2023-09-22T02:24Z

CME Note: CME seen to the NE of SOHO LASCO C2/C3 and STEREO A COR2. Source is a filament eruption near AR 3435 (approximately (N08E17). The liftoff can be seen starting around 2023-09-22T01:28Z in SDO AIA 193/304. There is also an M1.2 flare just after the start of the filament eruption from this AR starting at 2023-09-22T02:25Z, followed by post-eruptive loops best seen in SDO AIA 131/193. Brightening can also be seen in this region in SDO AIA 304. Arrival signature: sharp amplification of magnetic field to 27nT and increases in solar wind speed from ~300 km/s to ~500 km/s, with subsequent increases in density and temperature. Alternatively, this could be the arrival of 2023-09-22T07:36Z CME or the combined arrival of these two CMEs.

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.
