Unsettled: Mar 3 - 5
Active: possible Mar 5 - 7
Minor storm:  0
Major storm: 0
Severe storm: 0

Geomagnetic activity summary:

Last night, a minor geomagnetic storm has been observed. We expect
geomagnetic activity decrease during the next week. First half of
forecasted week, we expect at most unsettled course (but tending to quiet
to unsettled conditions), the second half, we expect at most quiet
conditions only with isolated unsettled or singular active episode.
We do not expect any storming event next week.
