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
period. is the U.S. government's official web portal to all federal, state and local government web resources and services.
