Forecast of Solar and Geomagnetic Activity
20 May - 15 June 2013

Solar activity is expected to be low to moderate throughout the
forecast period. High levels of activity are possible through 25 May
and again after 7 June associated with Region 1748.

There is a chance for proton events at geosynchronous orbit,
particularly through 25 May and again after 7 June associated with
Region 1748.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels from 24-31 May associated with a
recurrent coronal hole high speed stream.

Geomagnetic field activity is expected to reach minor to major storm
levels on 20 May in response to the 17 May coronal mass ejection. In
the absence of any Earth-directed coronal mass ejections, the
remainder of the forecast period is expected to be characterized by
quiet to unsettled levels of activity with the possible exception of
28 May, when another geoeffective coronal hole high speed stream
becomes geoeffective and brings active levels.
