Prediction for CME (2023-11-22T21:36:00-CME-001)

CME Observed Time: 2023-11-22T21:36Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/27829/-1
CME Note: Southern directed CME as seen in LASCO C2/C3 and STEREO A COR2 imagery. Partial halo. Source is a faint and broad area of dimming spanning from about E20-W30 (near AR3489 to AR3498) starting at about 2023-11-22T20:45Z as seen in SDO AIA 171/193 and GOES SUVI 284 imagery. There was a C4.1-class flare from AR 3489 (S15E07) with peak time 2023-11-22T19:02Z associated with this event. Arrival signature is complex, with solar wind speed was jumping from 480 km/s to over 550 km/s, reaching a maximum near 600 km/s and a corresponding amplification of B_total from 7 nT to 18 nT and of density from 17 to over 25 particles/cc. The signature is complicated by the preceding arrival of a coronal high speed stream on 2023-11-24.

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.
