## Summary:
Significantly elevated energetic electron fluxes in the Earth's outer radiation belt. GOES "greater than 2.0 MeV" integral electron flux remains elevated, recently crossing the threshold of 1000 pfu at 2026-06-28T06:20Z.
The elevated energetic electron flux levels observed since 2026-06-26T13:45Z are likely caused by the arrival of the coronal hole high speed stream starting on 2026-06-24, reaching maximum sustained speeds of approximately 715 km/s, and the arrival of CME with ID 2026-06-19T03:53:00-CME-001 detected at L1 by SOLAR-1 at 2026-06-23T03:43Z and the arrival of CME with ID 2026-06-20T02:12:00-CME-001 detected at L1 by SOLAR-1 at 2026-06-24T04:05Z. The solar wind speed observed at L1 is currently around 450 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: 2026-06-26T13:45:00-RBE-001.
## Notes:
This coronal hole high speed stream is also associated with the modeled magnetopause crossing with ID 2026-06-24T21:35:00-MPC-001 (see notification 20260625-AL-001).

## Disclaimer: NOAA's Space Weather Prediction Center is the United States Government official source for space weather forecasts. This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
## 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 2026-06-26T13:45Z.
The elevated energetic electron flux levels are caused by the arrival of the coronal hole high speed stream starting at 2026-06-24, reaching maximum sustained speeds of approximately 715 km/s, and possibly the arrival of CME with ID 2026-06-19T03:53:00-CME-001 detected at L1 by SOLAR-1 at 2026-06-23T03:43Z and the arrival of CME with ID 2026-06-20T02:12:00-CME-001 detected at L1 by SOLAR-1 at 2026-06-24T04:05Z. The solar wind speed observed at L1 is currently around 630 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: 2026-06-26T13:45:00-RBE-001.
## Notes:
The arrival of this coronal hole high speed stream was associated with modeled magnetopause crossing with ID 2026-06-24T21:35:00-MPC-001 (see notification 20260625-AL-001). Simulations indicated that the magnetopause separating magnetospheric and solar wind plasma was close to the geosynchronous orbit starting at 2026-06-24T21:35Z.

## Summary:
Strong compression of the magnetosphere detected. Simulations carried out at NASA Community Coordinated Modeling Center indicate that the magnetopause separating magnetospheric and solar wind plasma is close to the geosynchronous orbit starting at 2026-06-24T21:35Z.
The activity is likely associated with the arrival of a coronal hole high speed stream on 2026-06-24.
NASA spacecraft at the geosynchronous orbits may be exposed to solar wind plasma and magnetic field conditions.
