Geomagnetic activity forecast for the period March 2 - March 8, 2018
Quiet: Mar 2 - 4, 8
Unsettled: Mar 5 - 7
Minor storm: 0
Major storm: 0
Severe storm: 0
Geomagnetic activity summary:
During the last days (February 26 - 27), we observed the forecasted active
episode but the local K-index did not exceed K=4. None storming effect has
Next week, we expect quiet to unsettled conditions. Till Sunday, March 4,
we expect at most quiet conditions only with minor unsettled events. The
second half of forecasted period, the unsettled episodes can be more
frequent but the general geomagnetic activity should stay at quiet to

Geomagnetic activity forecast for the period March 2 - March 27, 2018
Geomagnetic field will be:
quiet on March 3, 6 - 7, 10, 12 - 13, 20
mostly quiet on March 11
quiet to unsettled on March 2, 5, 19, 23 - 24, 27
quiet to active on March 4, 8 - 9, 14 - 16, 21 - 22, 25
active to disturbed on March 17 - 19, 26
Amplifications of the solar wind from coronal holes: can not be predicted
for the period before March 10, but I do not expect any significant upsurge.
Then solar wind will intensify on March (10,) 16 - 18, (19 - 20, 25 - 26)
- Parenthesis means lower probability of activity enhancement.
- With regard to ongoing changes, current forecasts remains less reliable
especially in the first half of March.
