Prediction for CME (2021-12-15T05:00:00-CME-001)

CME Observed Time: 2021-12-15T05:00Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18534/-1
CME Note: This CME is associated with an eruption near AR 12907 (near S25E45) which exhibits dimming and a small EUV wave visible in SDO AIA 193 beginning 2021-12-15T01:30Z. Northward deflection of source is apparent in SDO's field-of-view. UPDATE (2021-12-24T18:17Z): Field component rotation indicating a potential flux rope buried in the 2021-12-19 high speed stream arrival signature, from 2021-12-19T18:28Z to 2021-12-19T20:35Z, may possibly be associated with the combined arrival of CMEs 2021-12-14T17:38Z and 2021-12-15T05:00Z. The overall solar wind signatures for density, speed, and temperature are dominated by the 2021-12-19 high speed stream arrival, with only small changes that might support the field signature.

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.
