Prediction for CME (2026-07-21T15:12:00-CME-001)
CME Observed Time: 2026-07-21T15:12ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/47725/-1
CME Note: [Preliminary] The arrival of this CME was not clearly detected at L1. This CME is visible to the northeast in STEREO A COR2 imagery, and is faint but may be seen to the northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The source may be related to an eruption/brightening from Active Region 14493 (N10W05) starting around 2026-07-21T12:00Z seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. There is a coronal hole north and south of this eruption site which may account for deflection from the on-disk source location.
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.
