Forecast of Solar and Geomagnetic Activity
19 September - 15 October 2016
Solar activity is expected to be at very low levels with a change
for C-class flares throughout the period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach very high levels on 02-05 Oct with high levels
expected on 21-25, 29 Sep-01 Oct, and 06-11 Oct following solar wind
enhancements associated with the influence of multiple coronal hole
high speed streams. Electron flux is expected to be at normal or
normal to moderate levels throughout the remainder of the period.
Geomagnetic field activity is likely to reach G2 (Moderate)
geomagnetic storm levels on 28-30 Sep and G1 (Minor) storm levels on
19-20 Sep and 01 Oct due to the anticipated influence of multiple,
recurrent coronal hole high speed streams. Active conditions are
expected on 21 Sep and 02-05 Oct with generally quiet or quiet to
unsettled conditions likely throughout the remainder of the period.
