Prediction for CME (2021-10-12T03:24:00-CME-001)

CME Observed Time: 2021-10-12T03:24Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/17947/-1
CME Note: Very faint partial halo W in C2,C3 (front not seen in COR2A b/c of a large overlapping data gap from 2021-10-11T19:23Z to 2021-10-12T09:23Z). Source: eruption from AR 2882 at N16W30 seen in AIA 193/304 starting after 2021-10-12T02:03Z and associated with multiple higher B-class flares from this active region and an EUV wave seen in AIA 193. Arrival indicated by sharp increase in B_total, reaching 9.76 nT at 2021-10-16T01:40Z, accompanied by pileup and speed increase, in addition to field component rotation indicating potential flux rope and momentary temperature rise indicating potential CME arrival. Kp increased to 3 during the 2021-10-16T00:00Z-03:00Z synoptic period in response but decreased afterward. Field remained amplified for two days following arrival, indicating a complex L1 solar wind signature that included both a far-flank flux rope interaction and a subsequent high-speed stream arrival.

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.
