Prediction for CME (2026-08-03T12:23:00-CME-001)
CME Observed Time: 2026-08-03T12:23ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/47943/-1
CME Note: CME observed to the SE in STEREO A COR2 and GOES CCOR-1. The source is a filament eruption on the south central disk centered around S35W05. The filament in SDO AIA 304 begins to lift as early as approx. 2026-08-03T03:00Z, erupting and dissippating from approx. 2026-08-03T07:00Z to 2026-08-03T12:00Z, with brightening on-disk. Also observed in SDO AIA 193 as a wide swath of dimming starting approx. 2026-08-03T10:00Z which migrates southeastward for several hours covering a large area of the south-central disk. Also observed as the filament, field line movement, dimming, and brightening in STEREO A EUVI 195/304 at 2026-08-03T07:55Z and 2026-08-03T08:15Z respectively. | Preliminarily closed out as non-arrival, investigating possible arrival around 2026-08-08T05:54Z.
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.
