X-ray background flux (1.0-8.0 A): in the range A3.5-A7.0
Radio flux (10.7 cm): a fluctuation in the range 67-78 f.u.
Events: class C (0/period), class M (0/period), class X (0/period), proton (0/period)

Geomagnetic activity forecast for the period December 1 - December 7, 2017
Quiet: Dec 2 - 4
Unsettled: Dec 1, 4, 7
Active: Dec 5 - 6
Minor storm: possible Dec 5 - 6
Major storm: 0
Severe storm: 0
Geomagnetic activity summary:
We expect the most active episode between December 4-5. We expect at most
active conditions during these days, a minor storming effect is also
possible.
The rest of the actual forecasted week, we expect at most quiet to
unsettled conditions. At most quiet conditions are expected during the
coming weekend (December 2-3). Quiet to unsettled conditions are expected
to the CH HSS expected at Wednesday, December 6.

Geomagnetic activity forecast for the period December 1 - December 27, 2017
Geomagnetic field will be:
quiet on December 2, 16, 23, 26
mostly quiet on December 1, 8, 14, 17, 21, 24 - 25
quiet to unsettled on December 3 - 4, 9 - 12, 15, 20, 27
quiet to active on December 7, 13, 18
active to disturbed on December 5 - 6, 19, 22
Amplifications of the solar wind from coronal holes are expected
on December (1 - 2, 4,) 5, 7 - 8, 17 - 20, (21 - 22, 24 - 25)
Remark:
- Parenthesis means lower probability of activity enhancement.
