Prediction for CME (2021-11-02T02:48:00-CME-001)

CME Observed Time: 2021-11-02T02:48Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18161/-1
CME Note: This CME is associated with a long-duration M1.6 flare from AR 12891 and a corresponding eruption signature can be seen in the available SDO AIA imagery toward the center of the Earth-facing disk as early as 2021-11-01T23:37Z. The shock was most probably caused by the combined arrival of this CME and the 2021-11-01T18:38Z CME and exhibited a dramatic increase in B_tot first to 14 nT at 2021-11-03T19:55Z and then to the maximum of 24 nT at 21:07Z, with corresponding increases in density, temperature, and solar wind speed (to speeds around 700 km/s, with a maximum of 809 km/s). There is a clear flux rope, accompanied by a drop in temperature the next morning. There was an associated magnetopause crossing and a strong geomagnetic storm, with 5 synoptic periods of Kp above 6 (three of them with Kp=7).

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.
