Geomagnetic activity
summary:
Geomagnetic field is currently quiet. We expected active
conditions
between July 2 - 4 when fast solar wind can influence the
Earth
magnetosphere. 27 days ago, active conditions reached locally K=5
(Budkov
observatory) but it is less probable.
After the possible active
episode, we expect return of quiet to unsettled
conditions to the end of
forecasted time.
