CME Observed Time: 2021-11-24T14:09ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18362/-1
CME Note: Visible in the SW in STEREO A COR2 and in the S in SOHO LASCO C2. Associated with an eruption near S30E20. Dimming and post-eruptive arcades visible in SDO AIA 171/193/304 and EUVIA 195/304 beginning 2021-11-24T13:00Z. CME arrival marked by a sudden increase in B total, which reached 17 nT. Density and temperature also increased during the shock and pileup. The solar wind increased from 300 km/s to 380 km/s during the shock.

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.
