Forecast of Solar and Geomagnetic Activity
09 February - 07 March 2015

Solar activity is expected to be at predominately low to moderate levels throughout the period with only low levels of solar activity expected for 14-15 Feb. Low to moderate solar activity is expected
for the remainder of the period as Region 2280 (S07, L=283) continues its transit of the visible disk and as Region 2268 (S11, L=048) and Region 2277 (N08, L=330) return on 16 Feb and 22 Feb,
respectively. Regions 2268 and 2277 were previously credited with R1 (Minor) radio blackout event production during their previous appearance to the visible disk. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach moderate levels on 09-11, 17, 19-21, and 25 Feb a  well as 01 and 05-07 Mar with high levels anticipated on 02-04 Mar
in response to coronal hole high speed stream (CH HSS) influence. 

Geomagnetic field activity is expected to be at predominately quiet to unsettled levels throughout the outlook period with periods of active conditions expected on 15, 17, 22-23 Feb and 02 Mar with
isolated periods of G1 (Minor) geomagnetic storm conditions likely on 28 Feb and 01 Mar, all due to recurrent CH HSS effects.
