## 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 2026-03-22T16:23:00-CME-001 (see previous notification 20260323-AL-001).
Based on heliospheric ensemble modeling carried out at the Moon to Mars Space Weather Analysis Office, it is estimated that the CME may impact NASA missions near Earth. Out of 26 ensemble members (see notes section), 5 (19%) indicate impact at NASA missions near Earth. Ensemble simulations indicate that the leading edge of the CME will reach NASA missions near Earth between about 2026-03-25T01:45Z and 2026-03-25T10:23Z (average arrival 2026-03-25T05:31Z). The ensemble-based forecast indicates that there is a 60% chance for the maximum Kp index to be in the 3-5 range (below minor to minor).

## Notes:
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.

## 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 2026-03-22T14:15Z.
The elevated energetic electron flux levels may be caused by the arrival of the CME with ID 2026-03-18T09:23:00-CME-001 as detected at L1 by ACE at 2026-03-20T20:17Z (see notifications 20260318-AL-002, 20260318-AL-003, 20260320-AL-004). Additional influence may be caused by the arrival of a coronal hole high speed stream starting on 2026-03-21, reaching a maximum sustained speed of approximately 640 km/s. The solar wind speed observed at L1 is currently around 575 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.
