Geomagnetic
activity forecast for the period November 18 - November 24,
2016
Quiet: Nov 18
Unsettled: Nov 18 - 20, 24
Active: Nov 22 -
24
Minor storm: probable Nov 21 - 22
Major storm:possible Nov 21
Severe
storm: 0
Geomagnetic activity summary:
The first trhee days, we expect
still quiet to unsettled conditions. We
expect the active conditions at he
second half of forecasted period when
the activity can reach major storm
level. The maximum of geomagnetic
activity (minor to major storm) is expected
at Nov 21, the local K-index
at the Budkov observatory can reach or exceed
K=5. The following days, we
expect unsettled to active conditions and, the
last one, decrease to
unsettled level.
