The high energy electron flux (greater than 2MeV) at geosynchronous Earth orbit may peak above the Active level through the period around the diurnal maximum. Perhaps with a generally decreasing trend, although falling confidence.  The 24-hour fluence is now expected to remain below the Active threshold (1e8 integrated pfu) throughout.

This forecast is supported by the REFM forecast. The 27-day recurrence doesn't offer much guidance, as on the previous rotation fluence levels were higher for longer. The arrival of a CIR on Day 1 may also cause levels to fall as the outer Van Allen belt is compressed.
