It's going to be another "up and down" month with recurrent coronal hole high speed streams (CH HSS) forecast to drive the Ap up three times during the period, along with another unsettled/active period 27-29 September.  Solar Flux should be best 06-17 September, with quiet conditions during most of that period.

Forecast of Solar and Geomagnetic Activity
26 August - 21 September 2013

Solar activity is expected to be at very low to low levels. A chance
for an M-class flare exists with the return of old Region 1817 (S21,
L=241) from 02-15 September. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be normal to moderate levels with high levels expected
on 27-29 August, 02-07 September, 12-16 September, and again on
19-21 September due to activity associated with recurrent CH HSSs. 

Geomagnetic field activity is expected to be mostly quiet with the
exception of quiet to unsettled levels on 26-27 August and 05
September due to CH HSS activity. Unsettled to active levels are
expected on 31 August - 02 September, 10-14 September, and again on
17-19 September due to recurrent CH HSS activity.
