Prediction for CME (2021-01-02T11:24:00-CME-001)
CME Observed Time: 2021-01-02T11:24ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/16304/-1
CME Note: This CME is preceded by the 2021-01-01T22:00Z CME. An eruption signature is visible in SDO AIA 193/304/171, showing some dark filament material rising from approximately S40W15 beginning around 2021-01-02T09:00Z with rising material/opening field lines also visible beyond the western limb in the view of STA EUVI 195. This is followed by a clear liftoff of filamentary material in SDO AIA 304 at 10:45Z, and then significant darkening seen along the entire filament from ~S10 to S40 and W00 to W30 beginning around 11:00Z. The effects of this CME are likely combined with the 2021-01-01T22:00Z CME. ARRIVAL SIGNATURE: From Lan Jian: This event should be a HSS with CME embedded. There seems to be a sector boundary at about Jan. 5 12UT. The smooth magnetic field rotations concur with the second B pile-up and second Vp increase. I dont see a shock associated with the event. The flux rope part is from about 0 to 6 UT on Jan. 6. It is possible Earth only encountered the CME at the flank.

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.
