Forecast of Solar and Geomagnetic Activity
23 May - 18 June 2016

Solar activity is expected to be very low (B-class flares) to low
(C-class flares) levels throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 28-29 May, 01 Jun, 03-09 Jun, 12-13
Jun, and 18 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 04 Jun and G1 (Minor) geomagnetic storm
levels on 05 Jun due to the influence of a negative polarity CH HSS.
Active geomagnetic levels are expected on 26 May, 30-31 May, 02-03
Jun, 06 Jun, 11-13 Jun, and 17-18 Jun due to various recurrent CH
HSSs.
