Prediction for CME (2026-05-28T09:23:00-CME-001)
CME Observed Time: 2026-05-28T09:23ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/46442/-1
CME Note: Faint CME visible well to the E in STEREO A COR, and as a faint partial halo in SOHO LASCO C2/C3 and GOES CCOR-1 comprised of multiple overlapping features, clearly a complex structure. This front may be related to a slow, faint dimming in SDO AIA 193 as early as 2026-05-28T01:57Z centered around S33E28 south of AR 14436 (S16E29), which is more directly attributed to earlier CME: 2026-05-28T03:38Z but this front at T9:23Z resembles more of streamer blowout and could simply be outflow following from that first signature. No distinct eruptive activity is seen relating to this start time.
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.
