Forecaster summary - Issued 2021-09-04T00:28:49

High energy electron flux is currently oscillating between moderate and high (1e3pfu) on diurnal maximums, but this pattern is expected to follow a declining trend through the next four days as electrons slowly dissipate from the radiation belts. This is combined with an expected decline in the solar wind speeds, reducing any additional input into the belts. A potential coronal hole interaction on day 3 is considered to be low risk and unlikely to provide significant electron input.

Electron fluence values are below the Active (1e8 integrated pfu) with a declining trend, which is expected to continue through much of the forecast period, with no significant input into the radiation belts.
