MOSWOC high energy electron forecast for geostationary orbit

Forecaster summary - Issued 2021-10-15T00:07:47

The high energy (greater than 2 MeV) electron flux has been at Normal Background to Moderate levels, with generally no change expected within the forecast period, although a gradually increasing trend is likely with the potential arrive of a weak CME and also a weak high speed stream.

With no significant coronal hole feature during the previous rotation, and none currently present in the western hemisphere, with just the potential for a weak high speed stream from former CH12, the persistence model appears to be offering good guidance with the forecast fluence remaining below Active levels.
