Geomagnetic activity forecast for the period October 2 - 28, 2015

Geomagnetic field will be:
quiet on October 22 - 26
mostly quiet on October 18 - 20
quiet to unsettled on  October 4 - 6, 9 - 10, 15, 21, 27 - 28
quiet to active on October 2 - 3, 11 - 14, 16 - 17
active to disturbed on October 7 - 8

Amplifications of the solar wind are expected on October 2 - 3, 7 - 10, 16 - 17


Remarks:
- Reliability of predictions remains reduced in present solar cycle phase.
- Parenthesis means lower probability of activity enhancement.
