Forecast of Solar and Geomagnetic Activity
23 October - 18 November 2017

Solar activity is expected to be at very low to low levels with a
slight chance for M-class flares (R1-Minor) on 23-06 Nov due to
potential flare activity from Region 2685 and the return of old
Region 2683 (N13, L=111) to the visible disk. From 07-18 Nov, only
very low levels are expected.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
likely to be at high levels on 25-26 Oct, 28 Oct-01 Nov, 08-10 Nov,
12 Nov, 15 Nov and 17 Nov with very high levels on 27 Oct, 11 Nov
and13-14 Nov due to CH HSS influence.

Geomagnetic field activity is expected to be unsettled to active
levels on 24-29 Oct, 01-02 Nov, 07-11 Nov and 15-17 Nov with G1
(Minor) storm levels likely on 24-26 Oct, 07-11 Nov and G2
(Moderate) levels likely on 25-26 Oct and 09-10 Nov due to recurrent
CH HSS effects.
