Forecaster summary - Issued 2018-06-05T00:23:38

The high energy electron flux at geosynchronous orbit is expected to persist above the Active level for much of the period with peaks above Very Active at the maximum of the diurnal cycle. The corresponding 24-hour fluence is expected to remain above Active level (1e8 integrated pfu) through the period in response to recent high solar wind speeds, with a chance of Very Active levels during Day 1 or 2. The REFM model forecast is beginning to come back into line with recent Active-level observations. The recurrence from the previous rotation also supports Active levels through the forecast period, with an indication that Very Active fluence levels are possible. Levels remained above Active for over a week.
