MOSWOC high energy electron forecast for geostationary orbit

Forecaster summary - Issued 2021-11-29T00:29:24

The high energy (greater than 2 MeV) electron flux as observed by GOES-16 at GEO has been mainly background during the last 24 hours, and is expected to be at background to moderate levels through the period. The next main enhancement is likely to be from the fast wind of CH25 or CH26, potentially increasing levels to High on day 4 (2nd), however confidence is low. Other enhancements to the solar wind on days 1-2 are currently not expected to lead to high flux levels being observed. 

With flux remaining below the High level until at least day 4, the associated 24 hour integrated fluence is expected to remain below the Active threshold, with only a slight chance of rising above at the end of the period (2nd). This is supported by REFM which maintains fluence levels at well below the Active threshold.
