Forecast of Solar and Geomagnetic Activity
24 April - 20 May 2017

Solar activity is expected to be very low with a chance for C-class
flare activity throughout the outlook period (24 Apr-20 May).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
likely to reach very high levels on 29-30 Apr with high levels
likely on 24-28 Apr and 06-12, 17-20 May. Normal to moderate flux
levels are expected for the remainder of the period.

Geomagnetic field activity is likely to reach G2 (Moderate)
geomagnetic storm levels on 19-20 May with G1 (Minor) geomagnetic
storms likely on 24-27 Apr and 01, 17-18 May due to the influence of
multiple, recurrent CH HSSs. Active conditions are likely on 28 Apr
and 05-06, 16 May with quiet or quiet to unsettled field activity
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.
