CME Scoreboard: Prediction Detail

Prediction for CME (2026-02-25T07:38:00-CME-002)

CME Observed Time: 2026-02-25T07:38Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/44830/-1
CME Note: Faint CME seen only in STEREO A COR2 coronagraph to the E. It is covered by a data gap in SOHO LASCO imagery and is not seen in GOES CCOR-1 imagery. Its source is likely the C2.6 flare peaking at 2026-02-25T06:56Z (S08W27), with an associated minor-size eruption seen in SDO AIA 193/304 as brightening/dimming and post-eruptive arcades. There is also a type II radio emission associated with this event.
CME was not detected at Earth.

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.
