The arrival of the fast wind of coronal hole 62 during day 1 is expected to gradually increase the high energy Electron flux values observed at GEO, similar to those observed on the previous solar rotation. Whilst both REFM and also the potential for a any geomagnetic activity suggests that this is likely to be a gradual process at first, this will lead to the associated fluence levels climbing through the period. Consequently Active electron fluence levels will become increasingly possible by day 3, and likely by day 4.
