Prediction for CME (2023-02-17T20:23:00-CME-001)

CME Observed Time: 2023-02-17T20:23Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/23802/-1
CME Note: Asymmetric halo CME associated with X2.2 flare from AR3229 (N25E65) at 17/1957UT, with an EUVI wave and with the eruption seen as dimming (as far east as -20 deg), best noticeable in STEREO A EUVI 195. The bright bulk of the CME seems to have gone in the more Eastern direction. The likely arrival of this CME is signified by a sharp increase in magnetic field to 14 nT, accompanied by a sudden jump in ion density to over 17 particles/cm^3 and of the solar wind speed from 370 to 430 km/s.

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.
