Forecaster summary - Issued 2025-06-28T00:16:01

Electron flux has reached diurnally high levels following the easing of fast winds and geomagnetic activity from CH60/-. These fast winds served to charge the Van Allen belts over the past few days and as the solar wind pressure eases further, electron flux levels will likely increase, perhaps brining persistent high flux for a number of days.

MOSWOC REFM has been over-forecasting fluence levels over the past 48 hours, likely due to CME pollution on the previous rotation and later arrival of the fast winds of CH59/- and CH60/-. This lowers confidence in the evolution, but on balance eventual exceedance seems Likely through the next 3 days (28-30 Jun) before relaxing by day 4 (01 Jul).
