Prediction for CME (2023-09-22T07:36:00-CME-001)

CME Observed Time: 2023-09-22T07:36Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/27045/-1
CME Note: Faint CME seen to the NNW in SOHO LASCO C2/C3 and STEREO A COR2. The CME fades away quickly in SOHO LASCO C3 imagery, and the leading edge is diffuse. Source location is likely an eruption centered around N27W02 starting around 2023-09-22T06:00Z best seen as dimming in SDO AIA 193. Arrival signature: sharp amplification of magnetic field to 27nT and increases in solar wind speed from ~300 km/s to ~500 km/s, with subsequent increases in density and temperature. Alternatively, this could be the arrival of 2023-09-14T07:24Z CME or possibly the combined arrival of these two CMEs.

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.
