Solar activity is expected to be at very low levels. A chance for
C-flares is likely on 19 Oct-03 Nov with the return of old Regions
2682 (S10, L=126) and 2683 (N13, L=111).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high to very high levels on 16-18 Oct and again on
27 Oct and 11 Nov. High levels are expected on 19-21 Oct, 25-26 Oct,
28 Oct-01 Nov and on 08-10 Nov due to recurrent CH HSS influences.

Geomagnetic field activity is expected to be at unsettled to active
levels on 16-22 Oct, 24-29 Oct, 01-02 Nov, and 07-11 Nov. G1 (Minor)
geomagnetic storm levels are likely on 24-25 Oct and 07-11 Nov and
G2 (Moderate) levels are likely on 25 Oct and 10 Nov due to
recurrent CH HSS effects. is the U.S. government's official web portal to all federal, state and local government web resources and services.
