Geomagnetic activity
summary:
Solar wind velocity has currently decreasing course. After the last
active
episode (at the midnight Jul 19/20, the local K-index reached at
the
Budkov observatory value=5), we expect turning the geomagnetic
conditions
to quiet to unsettled. About Jul 26, an isolated active episode
is
possible. We do not expect storming events next week.
