Forecaster summary - Issued 2018-12-04T00:29:07

The high energy (greater than 2MeV) electron flux at GEO has been at background levels, but may increase to high on any diurnal peaks as a result of the high speed stream from coronal hole 53 early on day 1 before gradually decreasing. This is subject to potential increases in geomagnetic activity due to any interaction with the 30 November CME.

Corresponding electron fluence values would increase in response to the increase in flux values, with Active levels later in the period, most likely on days 3 or 4. Again any increase would be subject to geomagnetic enhancements as detailed in the flux commentary.
