Prediction for CME (2025-12-05T07:09:00-CME-001)

CME Observed Time: 2025-12-05T07:09Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/43276/-1
CME Note: Faint but clear loop seen in multiple timestamps of STEREO A COR2. There is potentially a very faint NNE front in SOHO LASCO C2 starting at 2025-12-05T07:48Z, but the front is not seen in C3 and GOES CCOR-1 (possibly because it is too faint). No clear source has been found in EUV 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.
