:
The geomagnetic field will be:
quiet on January 18-21, 25, 27, February 1, 7-9 mostly quiet on January 22, 24, 26, 31, February 4 - 6, 12 quiet to unsettled on January 23, 30, February 2-3, 10-11 quiet to active on January 28 active to disturbed on Janaury 29
Growing solar wind may cause remarkable changes in the magnetosphere and in the ionosphere on January 27-31, February 11-13. Remarks: Parenthesis mean a lower probability of activity enhancement. If until April 2014 (possible secondary maximum) solar activity will not reach a similar or higher level than in November 2011, then 2012 will remain to be the maximum of the 24th cycle (R = 70) - and vice versa.

Solar and geomagnetic forecast for the period of January 17, 2014 - February 12, 2014 ================================================
Solar activity will continue to fluctuate at solar flux levels of about 110-180 s.f.u. during the next few weeks. A common occurence of class C flares and of some class M flares is expected, class X flares are exceptionally possible.
The geomagnetic field will be:
quiet on January 18-21, 25, 27, February 1, 7-9 mostly quiet on January 22, 24, 26, 31, February 4-6, 12 quiet to unsettled on January 23, 30, February 2-3, 10-11 quiet to active on January 28 active to disturbed on January 29
