Geomagnetic
activity summary:
Hand-to hand with solar wind velocity decrease, the
geomagnetic activity
is turning to quiet conditions although we observed some
isolated active
episodes (at Budkov observatory, K=4 had been observed March
4, 5, 6 and
8), except of this, the activity was at most to quiet to
unsettled level.
Next period, we expect at most quiet to unsettled conditions
till March
16. This day, we expect active episode arrival which can reach
minor storm
level. Till this, especially between March 11 and 14, we expect
quiet
conditions.

Geomagnetic field will be:
quiet on March 14 - 15, 21, 26
mostly quiet on March 10 - 13, 20
quiet to unsettled March 16, 22, 25,
April 4
quiet to active on March 18 - 19, 24, 27 - 29, 31, April 1 - 3,

Amplifications of the solar
wind from coronal holes are expected
on March (20 - 22,) 23 - 27, (April 3 -

Remark:
- Parenthesis means lower probability of activity
enhancement and/or
lower reliability of prediction.
