Forecast of Solar and Geomagnetic Activity
27 March - 22 April 2017

Solar activity is expected to be at very low levels with a chance
for isolated C-class flares from Region 2644 during its transit
across the visible disk from 27 March - 04 April.

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 likely
from 29 March - 11 April and again from 18-22 April due to CH HSS

Geomagnetic field activity is expected to be at unsettled to active
levels from 27 March - 06 April and 17-19 April with G1 (Minor)
storm levels likely on 27-31 March and 17-18 April. G2 (Moderate)
storm levels are likely on 28-29 March. Heightened activity during
these periods is due to recurrent CH HSS effects. Quiet conditions
are expected for the remainder of the forecast period. is the U.S. government's official web portal to all federal, state and local government web resources and services.
