Prediction for CME (2025-10-23T16:38:00-CME-001)

CME Observed Time: 2025-10-23T16:38Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/42035/-1
CME Note: This CME is visible to the east in STEREO A COR2 imagery and may be faintly visible to the southwest in SOHO LASCO C2 imagery. The source is speculative but may be related to an eruption from Active Region 14256 (S16W22) starting around 2025-10-23T15:45Z as seen in GOES SUVI 195/284/304 and STEREO A EUVI 304 imagery.

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.
