Forecast of Solar and Geomagnetic Activity
28 September - 24 October 2015
Solar activity is expected to be at low to moderate levels from 28
Sep - 03 Oct due to flare potential from Regions 2420, 2421 (N17,
L=120, class/area Dac/110 on 26 Sep), and 2422. Very low to low
levels are expected from 04-14 Oct. A chance for moderate levels
returns from 15-24 Oct as Region 2420 is anticipated to rotate back
onto the visible disk.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels with high levels
possible on 03 and 06 Oct, 09-15 Oct and 18-24 Oct following
recurrent CH HSS events.
Geomagnetic field activity is expected to be at mostly quiet to
unsettled levels. Active periods are likely on 01-02 Oct, 04-05 Oct,
07-09 Oct, and 16-17 Oct due to recurrent coronal hole high speed
