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

quiet
conditions only with isolated unsettled or singular active
episode.
We do not expect any storming event next week.
