The high energy electron flux (greater than 2MeV) in the outer Van Allen belt at geostationary orbit is likely to continue well below Active levels through the next two days, but may rise towards the Active level on Day 3 and 4 (14th and 15th June), possibly rising above the 1000 pfu threshold at the diurnal maximum. The corresponding 24-hour fluence is also likely to remain below the Active threshold (1e8 integrated pfu) throughout. The REFM model is now showing  only a modest rise in Electron Fluence over the next few days. The 27-day recurrence also strongly indicates a low trend is the most likely outcome for the next two days, but with low chance of a rise on Days 3 and 4.
