Prediction for CME (2026-06-03T07:23:00-CME-001)

CME Observed Time: 2026-06-03T07:23Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/46596/-1
CME Note: This CME is visible as a partial halo to the north/northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery, and to the northeast in STEREO A COR2 imagery. The source is an M7.7 flare from Active Region 14455 (N14W13) starting around 2026-06-03T07:00Z as seen in SDO AIA 131/171/194/304, GOES SUVI 131/171/195/284/304 imagery, and STEREO A EUVI 195/304 imagery. A large ejecta is associated with this event which is deflected to the northwest. Additionally, an EUV wave is observed moving northwest of the eruption site, as seen in SDO AIA 171/193 and GOES SUVI 171/195/284 imagery. L1 arrival is likely to be 3 merged CMES 2026-06-03T11:48Z, 2026-06-03T07:23Z, 026-06-03T01:53Z.

CCMC 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.
