Forecast of Solar and Geomagnetic Activity
13 April - 09 May 2015
Solar activity is likely to be at moderate (R1-R2/Minor-Moderate)
levels throughout the period, with the exception of 25-26 April, due
to the flare potential of Regions 2320 (S12, L=211) and 2321 (N13,
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 reach high levels on 21-24 April and 04-09 May, moderate
levels on 17-20, 25-28 April, and 01-03 May, and normal levels for
the remainder of the period.
Geomagnetic field activity is expected to be at G1 (Minor)
geomagnetic storm levels on 17 and 30 April with active conditions
expected for 16, 25, 29 April and 01 May, all due to coronal hole
high speed stream effects. Quiet to unsettled field activity
expected for the remainder of the period.
