CME Observed Time: 2025-12-01T02:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/43155/-1
CME Note: Halo CME first seen to the NE by SOHO LASCO C2 beginning at 2025-12-01T02:48Z, as well as by SOHO LASCO C3, STEREO A COR and GOES CCOR-1 in later frames. The source of this event is an X1.9 class flare which peaked at 2025-12-01T02:49Z located at approximately N23E90. This flare is visible in GOES SUVI 131, along with wide field line opening seen in GOES SUVI 171, 195 and 284. Filament ejecta is also visible from this region in association with the flare in GOES SUVI 304.
CME was not detected at Earth.

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.
