Forecast of Solar and Geomagnetic Activity
01 September - 27 September 2014
Solar activity is expected to be at low levels with a slight chance
for M-class (R1-R2, Minor-Moderate) flaring from 01-09 September.
Beginning on 10 September and lasting through the end of the
forecast period, M-class flare probabilities are expected to
increase to a chance as old Regions 2146, 2149, and 2151 (S08,
L=253, class/area Cso/140 on 25 August) return to the visible disk.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 01-03, 07-09, and 27 September due
to CH HSS influence.
Geomagnetic field activity is expected to reach unsettled to active
levels from 01-08, 13, and 25-27 September due to CH HSS activity as
well as possible recurrent solar sector boundary crossings.
