Forecast of Solar and Geomagnetic Activity
21 May - 16 June 2018

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

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach very high levels on 05-07 Jun with high levels
expected on 02-04 and 08-13 Jun. Moderate flux levels are expected
for the remainder of the outlook period.

Geomagnetic field activity is expected to reach G2 (Moderate)
geomagnetic storm levels on 02 Jun and G1 (Minor) storm levels are
expected on 01 Jun due to the influence of a recurrent, negative
polarity coronal hole/high speed stream. Active conditions are
expected on 23 May and 03-05 Jun.
