The high energy electron flux (greater than 2MeV) is likely to remain at mainly high levels (above 1000pfu) throughout the period, perhaps with some reductions on days 2 and 3 (26th and 27th) in response to any enhanced geomagnetic activity due to coronal hole effects.

The corresponding fluence, currently well above the Active threshold (1e8 integrated pfu), is showing a slowly declining trend, and may dip below the Active threshold (1e8 integrated pfu) later on day 2 or day 3 (26th and 27th) should there be any enhanced geomagnetic activity in response to a High Speed Stream from CH91.
