## Community Coordinated Modeling Center Database Of Notifications, Knowledge, Information ( CCMC DONKI ) ## Message Type: Space Weather Notification - CME (Lucy, BepiColombo) ## ## Message Issue Date: 2026-06-12T23:49:35Z ## Message ID: 20260612-AL-003 ## ## Disclaimer: NOAA's Space Weather Prediction Center is the United States Government official source for space weather forecasts.

Start time of the event: 2026-06-12T19:24Z. Estimated speed: ~518 km/s. Estimated opening half-angle: 37 deg. Direction (lon./lat.): -80/0 in Heliocentric Earth Equatorial coordinates. Activity ID: 2026-06-12T19:24:00-CME-001 Based on preliminary analysis by the Moon to Mars Space Weather Analysis Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that the CME may impact Lucy (minor impact) and BepiColombo. The leading edge of the CME will reach Lucy at 2026-06-30T17:00Z and BepiColombo at 2026-06-14T04:46Z (plus minus 7 hours).
