Forecaster summary - Issued 2018-06-24T00:19:12

Due to the effects of geomagnetic activity from coronal hole 03, the high energy (greater than 2MeV) electron flux is forecast to be at mainly moderate levels, with a slight chance of reaching high levels in line with the diurnal cycle. There is then expected to be a sharp reduction in electrons due to the onset of the high speed stream from coronal hole 03 on day 4 (27 June).

The corresponding 24-hour integrated fluence is forecast to remain below the Active (1e8 integrated pfu) threshold through the forecast period based on persistence from the previous rotation and expected geomagnetic effects.
