Forecaster summary - Issued 2019-12-10T00:06:30

The high energy (greater than 2MeV) electron flux is currently at normal background levels, with a recent downward trend in the wake of Unsettled geomagnetic activity overnight on Sunday 08 into Monday 09 December.

There is currently just one feature on the entire solar disc that has proved capable of challenging the 'Active' 24-hour integrated electron fluence threshold - a large equator-spanning coronal hole - and that is not due until around 17/18 December. Neither CH89 nor 90 are expected to result in Active fluence, although the probability does rise very slightly in response to the latter by day four.
