The high energy electron flux (greater than 2MeV) is expected to average above the Active level during the period, but probably slowly decline. Therefore the corresponding 24-hour electron fluence is expected to persist at above Active levels at least on Days 1 and 2, but with reducing confidence on Days 3 and 4. The REFM model is suggesting a gradual decline over the next three days, but the measured fluence value is currently running comfortably ahead of the model. The 27-day recurrence is not of much use as the previous cycle fluence level was below the Active threshold during the equivalent period.
