Forecast of Solar and Geomagnetic Activity
20 April - 16 May 2015

Solar activity is expected to be very low to low with a slight
chance for moderate (R1-R2/minor-moderate) levels through 24 April
due to the flare potential from Region 2321. Very low to low levels
are expected from 25 April through 06 May. From 06-16 May, activity
levels are expected to increase to a chance for
(R1-R2/minor-moderate) levels upon the return of old Region 2321
(N11, L=092).

No proton events are expected at geosynchronous orbit, barring any
significant flare activity.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels from 20 April-06 May,
normal to moderate levels from 07-12 May and moderate to high levels
from 13-16 May.

Geomagnetic field activity is expected to be at G1 (minor)
geomagnetic storm levels on 21 and 22 April due to CME effects.
Field activity is expected to be at G1 (minor) geomagnetic storm
levels on 14 May with unsettled to active conditions expected on 20,
25, 29-30 April and 01, 13 and 15 May, all due to CH HSS effects.
Quiet to unsettled field activity is expected for the remainder of
the outlook period. is the U.S. government's official web portal to all federal, state and local government web resources and services.
