Prediction for CME (2026-03-21T21:36:00-CME-001)
CME Observed Time: 2026-03-21T21:36ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/45241/-1
CME Note: Semi-faint CME visible to the S/SE in SOHO LASCO C2/C3, GOES CCOR-1 and to the SE in STEREO A COR2 imagery. The source of this CME appears to be a slow moving/opening of field lines and dimming/brightening in the SE quadrant of the Earth-facing disk starting around 2026-03-21T18:30Z as seen in GOES SUVI 195, 304, and 284 centered around S45E30. There is a second eruption visible near S60W50 which may contribute to overlapping features in the outflowing part at the back of the CME starting around 2026-03-22T00:30Z as seen in GOES SUVI 304 and 195.
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.
