Prediction for CME (2026-07-20T19:53:00-CME-001)
CME Observed Time: 2026-07-20T19:53ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/47691/-1
CME Note: [Preliminary] The arrival of this CME was not clearly detected at L1. Thin, faint CME observed to the NE in STEREO A COR2 only, likely due to the GOES CCOR-1 occulting disk and real-time SOHO LASCO C2/C3 downlink gap (but also may be blocked by its occulting disk). The source is likely AR 14493, associated with an M1.1 flare in SDO AIA 131 peaking at 2026-07-30T19:20Z, also observed as brightening and field line movement in SDO AIA 171/193 and field line movement in STEREO A EUVI 195 near its east limb around 2026-07-20T19:55Z.
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.
