Prediction for CME (2025-12-30T07:23:00-CME-001)
CME Observed Time: 2025-12-30T07:23ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/43658/-1
CME Note: [PRELIMINARY] The arrival of this CME was not detected at L1. Faint CME seen to the NE in all three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1), with the faint front quickly becoming fuzzy/partially dissipating. The CME is somewhat overlapping with the more southern CME: 2025-12-30T07:00Z. A possible source is a narrow prominence/ejecta rotating northwardly seen starting at 2025-12-30T06:49Z in GOES SUVI 304 (and SDO AIA 304) on/behind the E limb (lat -15), however the fit between coronagraphs shows a much lower longitude, indicating AR 14324 (N25W33) as a possible source. There is a C3.5-class flare in this Active Region at the time.
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.
