Geomagnetic
activity forecast for the period November 20 - 26, 2015
Next week, we
expect at the Budkov observatory at most quiet to unsettled
conditions after
the current active episode. An unsettled to active
episode is possible at the
second half of the forecasted week but not very
much probable. We expect at
most local K-indices ≤ 3 with possibly
isolated active episode (K ≤ 4) in the
second half of forecasted week.

Geomagnetic
activity forecast for the period November 20 - December 15,
2015
Geomagnetic field will be:
quiet on November 21 - 25, 27 - 28,
December 9, 14
mostly quiet on November 20, December 11
quiet to unsettled
on November 26, 29, December 10, 12 - 13
quiet to active on December 4 - 6,
15
active to disturbed on November 30, December 1 - 3, 7 -
8
Amplifications of the solar wind are expected on November (20 -
22),
29 - 30, December (1,) 2, (5 - 7,) 8 - 10, (11 - 12, 16 -
20)
Remarks:
- Reliability of predictions unfortunately remains
reduced
in present solar cycle phase.
- Parenthesis means lower
probability of activity enhancement.
