Geomagnetic activity forecast for the period September 17 - 24, 2015
AT the Thursday, Sep 17, we expect quiet to unsettled geomagnetic
conditions. The same is our forecast for Friday, Sep 18.
Next days, Sep 19 - 20, we expect at most unsettled conditions with active

Geomagnetic activity forecast for the period September 18 - October 14, 2015
Geomagnetic field will be:
quiet on September 21, 27 - 28
mostly quiet on September 20, 26, 29, October 10, 14
quiet to unsettled on September 25, October 2, 7, 13
quiet to active on September 18 - 19, 23 - 24, 30, October 1, 3, 6, 9, 11
active to disturbed on September 22, October 4 - 5, 8, 12
Amplifications of the solar wind are expected on September (18,)
20 - 22, (25 - 28) and October 3 - 5, 8 - 9.
Remarks:
- Reliability of predictions remains essentially reduced in pesent solar cycle
phase.
- Parenthesis means lower probability of activity enhancement.
