Forecast of Solar and Geomagnetic Activity
12 October - 07 November 2015
Solar activity is expected to be at low levels throughout the period
with a chance for M-class flares (R1-R2 (Minor-Moderate) Radio
Blackouts) for 16-29 Oct due to the return of Region 2422 (S20,
L=102) which produced a total of 18 M-class flares last rotation.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be high levels on 12-15, 18-24 Oct, and 01-02, 04-07
Nov. Moderate flux levels are expected on 16-17, 25, and 27-28 Oct
with normal levels expected on 26, 29-31 Oct, and 03 Nov.
Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 12, 15-16 Oct, and 03 Nov due to the influence of
multiple recurrent coronal hole high speed streams (CH HSS). Active
levels are anticipated on 13-14, 17, 29 Oct, and 04-05 Nov. Quiet to
unsettled field activity is expected for the remainder of the
