Forecast of Solar and Geomagnetic Activity
20 February - 18 March 2017

Solar activity is expected to be at very low levels with a chance
for isolated C-class activity throughout the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 20-27 Feb and 01-13 Mar. Normal to
moderate levels are expected for the remainder of the outlook
period.

Geomagnetic field activity is expected to reach G2 (Moderate)
geomagnetic storm levels on 28 Feb and G1 (Minor) storm levels on 24
Feb, 01-02 Mar and again on 16 Mar due to recurrent CH HSS
influence. Active geomagnetic field activity is expected on 23 and
25 Feb, 03-05 Mar and 17 Mar due to CH HSS influence. Isolated
active conditions are likely on 22 Feb due to a glancing blow from
the 19 Feb CME. Quiet to unsettled activity is expected for the
remainder of the period under a nominal solar wind regime.
