CCMC CME Scoreboard
Prediction for CME (2026-05-26T22:36:00-CME-001)
CME Observed Time: 2026-05-26T22:36ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/46419/-1
CME Note: Very faint partial halo CME observed in SOHO LASCO C2 and GOES CCOR-1, also in LASCO C3 obscured heavily by the pylon (and difficult to observe outside running difference imagery in all). STEREO A COR2 in a data gap at this time. The source may be some field line movement and breaking loops observed around 2026-05-26T21:39Z to the SE only in GOES SUVI 284, tracing to an approximate source on-disk around S30E53 (and could vary slightly, due to the brightness of this cluster of regions in SUVI 284).
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.
