Geomagnetic
activity forecast for the period October 15 - 22, 2015
Next day (Oct 16)
we expect locally active conditions with minor storm
possible. Similarly,
active conditions are probable at Oct 18-19 with
minor storm possible, too.
Saturday, Oct 17, we expect at most unsettled
conditions.
Since Oct 19-20,
we expect geomagnetic activity decrease but the local
conditions still at
most unsettled.

solar cycle phase.
- Parenthesis means lower probability of activity
enhancement.
