Prediction for CME (2023-12-31T10:00:00-CME-001)
CME Observed Time: 2023-12-31T10:00ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/28405/-1
CME Note: CME NW in SOHO LASCO C2/C3 imagery visible for about three frames in STEREO A COR2 imagery prior to a data gap starting at 2023-12-31T10:53Z, after which the CME is out of the field of view. The source is a large filament eruption spanning N35W30 to N20W65 which begins to lift off around 2023-12-30T09:40Z as seen in SDO AIA 131, 171, 193, 304 imagery. Post-eruptive loops begin to form around 12:30Z in SDO AIA 171 and 193 as well. Most of the eruptive material appears to originate from the more western side of the filament. A possible arrival signature is characterized by an amplication of magnetic field with Btotal increasing from 7nT at 2024-01-03T04:50Z to ~12nT, an increase in solar wind speed from 415 to ~480 km/s, as well as a significant jump in density to over 18 pp/cm^3 and and increase in temperature are also observed. There is a likely arrival of the same CME at STEREO A hours earlier, indicating a westerly event.

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.
