Forecaster summary - Issued 2018-12-21T00:14:25

The high energy electron flux (greater than 2MeV) is currently at background to moderate levels.  With enhanced solar wind expected for the next few days but no significant geomagnetic activity anticipated, electron counts are expected to gradually rise over the next couple of days to reach moderate to high levels, then remain at these levels for the rest of the forecast period.

The corresponding 24-hour electron fluence is currently well below the High threshold (1e8 integrated pfu), but is expected to rise in response to increasing flux levels, with an increasing risk of approaching the High threshold (1e8 integrated pfu) later in the forecast period.
