Forecast of Solar and Geomagnetic Activity
23 April - 19 May 2018

Solar activity is expected to be very low throughout the forecast
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels on 23-30 Apr and 07-19
May; normal to moderate levels are expected from 01-06 May. Elevated
levels of electron flux are expected due to the anticipation of
multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to reach unsettled levels on
26 Apr, 06 May, 09-10 May and 19 May; active levels are expected on
27 Apr, 07-08 Apr and 18 May; G2 (Moderate) geomagnetic storm
conditions are likely on 17 May. All enhancements in geomagnetic
field activity are associated with the anticipated influence of
multiple, recurrent CH HSSs. The remaining days of the outlook
periods are expected to be mostly quiet.
