## Summary:
Significant interplanetary shock detected by ACE at L1 at 2026-05-07T15:16Z.
The shock may be associated with the arrival of a coronal hole high speed stream on 2026-05-07. Some magnetospheric compression likely and geomagnetic storm possible.

## Summary:
Update on CME with ID 2026-05-07T01:26:00-CME-001 (see previous notification 20260507-AL-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. The leading edge of the CME will reach Juno at 2026-05-21T00:00Z (plus minus 7 hours).
Previous simulations also estimate that the CME may affect Solar Orbiter (glancing blow). The flank of the CME will reach Solar Orbiter at 2026-05-09T10:00Z (plus minus 7 hours).
CME parameters are (C-type):
Start time of the event: 2026-05-07T01:26Z.
Estimated speed: ~798 km/s.
Estimated opening half-angle: 32 deg.
Direction (lon./lat.): -112/31 in Heliocentric Earth Equatorial coordinates.
