Forecaster summary - Issued 2018-12-27T00:02:11

The high energy electron flux (greater than 2MeV) is currently at background levels, and is expected to persist at mainly background to moderate levels, but perhaps increasing slightly reaching moderate to high levels during day 3 (29th) as the high speed stream becomes established.

The corresponding 24-hour fluence is currently well below the Active threshold (1e8 integrated pfu) and is forecast to remain steady around current levels until later on day 3 (29th), then may begin to show a gradual rising trend.  However it is most likely to remain well below the Active (1e8 integrated pfu) threshold throughout, albeit with decreased confidence by the end of the period.
