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.

Notes:
Asymmetric halo CME associated with X2.2 flare from AR3229 at 17/1957UT. A clear frontside eruption is visible in GOES SUVI 284 imagery.

The centre of the shock front passes behind STEREO-A. However, it is very broad, and modelling shows a clear impact with Earth.

Lead Time: 56.40 hour(s)
Difference: 19.87 hour(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.

If you are looking for the official U.S. Government forecast for space weather, please go to NOAA's Space Weather Prediction Center (https://swpc.noaa.gov). This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
