## 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 starting at 2025-07-01T08:10Z.
The elevated energetic electron flux levels observed since 2025-06-27T11:40Z are caused by a coronal hole high speed stream starting on 2025-06-25, reaching a maximum sustained speed of approximately 775 km/s (see notifications 20250627-AL-001 and 20250629-AL-002). The solar wind speed observed at L1 is currently around 490 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.

## Summary:
BETA PRODUCT. ENSEMBLE PRODUCT IS STILL IN DEVELOPMENT MODE. PLEASE LET US KNOW IF YOU HAVE ANY SUGGESTIONS FOR MODIFICATIONS.
Ensemble modeling update on CME with ID 2025-06-28T21:00:00-CME-001 (see previous notification 20250629-AL-001). Based on analysis by the Moon to Mars Space Weather Analysis Office and heliospheric ensemble modeling carried out at the Community Coordinated Modeling Center, it is estimated that the CME may impact STEREO A. For 32 ensemble members (see notes section), simulations indicate that the leading edge of the CME will reach:
- STEREO A between about 2025-07-01T05:31Z and 2025-07-01T09:45Z (average arrival 2025-07-01T08:03Z) for 25% of simulations.
Additionally the CME is estimated to reach NASA missions near Earth between about 2025-07-01T13:29Z and 2025-07-01T22:42Z (average arrival 2025-07-01T18:01Z) for 100% of simulations. The ensemble-based forecast indicates that there is a 73% chance for the maximum Kp index to be in the 4-6 range (below minor to moderate).

## Notes:
This CME event (2025-06-28T21:00:00-CME-001) is also predicted impact OSIRIS-APEX at 2025-07-01T03:30Z (plus minus 7 hours) based on previous heliospheric modeling (see notification 20250629-AL-001).
This CME event (2025-06-28T21:00:00-CME-001) is associated with C4.0 flare from Active Region 14126 (N07W22) with ID 2025-06-28T19:40:00-FLR-001 which peaked at 2025-06-28T19:54Z.
Ensemble CME modeling at M2M is performed by building sets of initial CME parameters and carrying out separate simulations for each set. This approach allows a mapping of initial CME parameter uncertainties into a statistical characterization of CME arrival times and impact at locations of interest.
Description of links: For each location, the first link shows the WSA-ENLIL+Cone model animation for the median CME input parameters, the second link shows the probabilistic distribution of predicted arrival times histogram, and the third link shows a stack plot of the WSA-ENLIL+Cone modeled magnetic field, velocity, density, and temperature for all ensemble members. For missions near Earth, a histogram of the probabilistic Kp forecast is also provided.
