Forecast of Solar and Geomagnetic Activity
25 April - 21 May 2016

Solar activity is expected to be very low to low for the majority of
the period with a chance for M-class flares from 03-16 May due to
the return of old Region 2529.

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 the exception of
01-03 May and 10-13 May following recurrent CH HSS events.

Geomagnetic field activity is expected to be quiet to unsettled on
25-26 Apr as CH HSS effects subside followed by quiet conditions on
27-28 Apr. Quiet to unsettled conditions are expected on 29 Apr to
01 May with active periods likely due to effects from a recurrent,
negative polarity CH HSS. An isolated minor storm period is possible
on 30 Apr. Mostly quiet conditions are expected on 02-08 May with
unsettled to active periods possible on 04 May due to a SSBC. Quiet
to active levels are expected on 09-11 May with minor storm periods
likely due to negative polarity CH HSS effects. Mostly quiet
conditions are expected from 12-18 May. Isolated unsettled to active
periods are possible on 14 May due to another SSBC. Quiet to
unsettled conditions are expected from 19-21 May with isolated
active periods possible due to effects from a recurrent, positive
polarity CH HSS.
