Geomagnetic activity forecast for the period April 26 - May 5, 2016

Quiet: Apr 26 - 28, May 2-3, 5
Unsettled: Apr 27 - 28, 30 and May 1, 4
Active:  Apr 29
Minor storm: possible but unlikely Apr 29
Major storm:0
Severe storm: 0

Geomagntic activity summary:
At the Budkov observatory, we expect quiet to unsettled conditions the
next three days. Friday, Apr 29, active conditions are expectable but the
local K-ndex at the Budkov observatory should not exceed K=4.
Sunday, May 1, we expect unsettled conditions. Next two days, Monday, May
2 and Tuesday, May 3, the expected geomagnetic conditions are quiet to
unsettled. The same conditions are probable at the end of forecasted time,
only about midnight May3/4, higher unsettled episode is possible. The last
day, May 5, we expect quiet to unsettled conditions.
