## Summary:
C-type CME detected by SOHO.
Start time of the event: 2026-03-16T09:24Z.
Estimated speed: ~728 km/s.
Estimated opening half-angle: 25 deg.
Direction (lon./lat.): -70/-32 in Heliocentric Earth Equatorial coordinates.
Activity ID: 2026-03-16T09:24:00-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 Juno (glancing blow). The flank of the CME may reach Juno at 2026-03-30T09:00Z (plus minus 7 hours).

## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux is above 1000 pfu starting at 2026-03-15T16:05Z.
The elevated energetic electron flux levels are caused by a coronal hole high speed stream starting on 2026-03-13, reaching maximum sustained speeds of approximately 700 km/s. The solar wind speed observed at L1 is currently around 615 km/s.
NASA spacecraft at GEO, MEO and other orbits passing through or in the vicinity of the Earth's outer radiation belt can be impacted.
Activity ID: 2026-03-15T16:05:00-RBE-001.
## Notes:
This coronal hole high speed stream is also associated with geomagnetic storm with ID 2026-03-13T21:00:00-GST-001.

## Summary:
A space weather storm has recently affected Earth's magnetosphere. Geomagnetic Kp index has reached level 6 (moderate) during the synoptic period 2026-03-14T03:00Z to 2026-03-14T06:00Z.
The storm is caused by coronal hole high speed stream starting on 2026-03-13.
NASA spacecraft at GEO, MEO, polar and other orbits passing through or in the vicinity of the Earth's ring current and auroral regions can be impacted.
Activity ID: 2026-03-13T21:00:00-GST-001.
## Notes:
This event is associated with Interplanetary Shock with ID 2026-03-13T07:06:00-IPS-001 (see notification 20260313-AL-001).
