Forecast of Solar and Geomagnetic Activity
16 December - 11 January 2014
Solar activity is expected to be at low levels with a chance for
M-class evens (R1 - minor - radio blackouts) through the period,
particularly with the return of Old Region 1913 on 18 Dec.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to begin the period at high levels through 18 Dec,
decreasing to normal to moderate levels for the remainder of the
Geomagnetic field activity is expected to reach active levels on
26-27 Dec, 03-04 Jan, and 10 Jan in response to recurrent coronal
hole high speed streams. Minor storm conditions may be possible on
04 Jan. Quiet to unsettled levels are expected for the remainder of
the forecast period in the absence of any transient features.
