Prediction for CME (2021-12-20T12:36:00-CME-001)

CME Observed Time: 2021-12-20T12:36Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18587/-1
CME Note: This CME is associated with an M1.8 from AR12908 (S20W00). It is visible in the south of SOHO LASCO C2/C3 and in the west of STEROE A COR. This CME has a dimpled front. The eruption is characterized by an EUV wave, dimming, and post eruption arcades. | Update: "There is no clear CME signature on Dec 24-25. During the short-duration mag field rotations, the field is not much increased or quiet." - Lan Jian

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.
