## Summary:
C-type CME detected by STEREO A.
Start time of the event: 2026-06-02T17:23Z.
Estimated speed: ~672 km/s.
Estimated opening half-angle: 14 deg.
Direction (lon./lat.): 5/9 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-06-02T17:23:00-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 this CME may affect Europa Clipper (minor impact), OSIRIS-APEX (minor impact), and Juice (glancing blow). The leading edge of the CME may reach Europa Clipper at 2026-06-07T02:00Z and OSIRIS-APEX at 2026-06-06T06:00Z (plus minus 7 hours). The flank of the CME may reach Juice at 2026-06-07T18:00Z (plus minus 7 hours).
The simulation also indicates that the CME may have a minor impact at NASA missions near Earth. Simulations indicate that the leading edge of the CME will reach NASA missions near Earth at about 2026-06-05T08:00Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-5 (below minor to minor).

## Summary:
C-type CME detected by STEREO A / GOES / SOHO.
Start time of the event: 2026-06-02T17:00Z.
Estimated speed: ~866 km/s.
Estimated opening half-angle: 36 deg.
Direction (lon./lat.): -121/26 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-06-02T17:00:00-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 Juno (minor impact), BepiColombo (glancing blow), and Solar Orbiter (glancing blow). The leading edge of the CME may reach Juno at 2026-06-15T12:00Z (plus minus 7 hours). The flank of the CME may reach BepiColombo at 2026-06-03T12:00Z and Solar Orbiter at 2026-06-04T16:00Z (plus minus 7 hours).
