CME Observed Time: 2021-12-20T05:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18584/-1
CME Note: This CME is visible in the east of SOHO LASCO C2 and C3. STEREO A COR2 data is not available. It is associated with a C4.4 flare from AR 12909 (S19E11) which peaked at 2021-12-20T03:21Z. This was followed by an eruption with dimming, an EUV wave, and post eruptive arcades in SDO AIA 193 and 171 beginning at 2021-12-20T03:15Z. The material is also seen leaving the disk in SDO AIA 304. The source signature is seen as opening field lines in SDO AIA 171. | 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.
