Forecast of Solar and Geomagnetic Activity
29 May - 24 June 2017

Solar activity is expected to be at very low levels throughout the
forecast period with a chance for further isolated C-class flares on
29-30 May due to flare potential from Region 2659.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels with high levels likely
from 29-30 May due to CME influence. High levels are also likely
from 16-24 Jun due to CH HSS influence.

Geomagnetic field activity is expected to be at quiet to active
levels on 29 May due to waning CME effects. Mostly quiet conditions
are expected from 30 May through 09 Jun. From 10-19 Jun, unsettled
to active levels are expected with G1 (Minor) geomagnetic storm
levels likely on 16 Jun due to recurrent CH HSS effects. Mostly
quiet conditions are expected to return from 20-24 Jun. is the U.S. government's official web portal to all federal, state and local government web resources and services.
