Prediction for CME (2026-04-23T05:12:00-CME-001)
CME Observed Time: 2026-04-23T05:12ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/45789/-1
CME Note: CME whose bulk is seen to the northeast with wider shock seen to due east in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 coronagraphs in association with a long duration M1.2 class solar flare from AR4420 near N16E40. The EUV signature is characterized by a circular EUV wave and dimming signature during the eruption seen best in SDO AIA 193 and GOES SUVI 284.

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.
