Forecaster summary - Issued 2018-09-01T00:13:25

The high energy electron flux (greater than 2 MeV) is currently at persistently high levels, and is expected to continue at these levels for much of the period. However peak levels of the diurnal cycle are now showing a gradual decline, and this trend is also expected to continue. This will lead to the 24 hour integrated fluence levels also gradually declining, and likely falling below the current very high levels during day 2 or 3. However Active fluence are expected to persist throughout. REFM supports these declining electron fluence values, however this is much too fast, especially beyond T+24.
