Solar
activity forecast for the period May 6 - May 12, 2016
Activity level: mostly very low to low
X-ray background flux (1.0-8.0 A): in the range A8.0-B4.0
Radio flux (10.7 cm): a fluctuation in the range 80-110 f.u.
Events: class C (0-5/day), class M (0-2/period), class X (0/period), proton (0/period)
Relative sunspot number (Ri): in the range 10-90

Geomagnetic activity forecast for the period May 6 - May 12, 2016
Quiet: May 5-6
Unsettled: May 7 - 8, 12
Active: May 8 - 10
Minor storm: possible May 10 - 11
Major storm:0
Severe storm: 0
Geomagntic activity summary:
Solar wind velocity has still decreasing course. Starting the new week, we
expect quiet conditions in the coming three days. At the end of weekend,
we expect active conditions arrival because of coronal hole HSS. The
active period is like between May 9-11 peaking at the Midnight May 10/11.
Minor storm occurence is in this time possible also at our latitudes.

Geomagnetic activity forecast for the period May 6 - June 1, 2016
Geomagnetic field will be:
quiet on May 7 - 8, 16 - 17, 26 - 28, June 1
mostly quiet on May 9, 14, 18, 22, 29, 31
quiet to unsettled on May 6, 13, 21, 23 - 25
quiet to active on May 12, 15, 19 - 20
active to disturbed on May 10 - 11, 30
Amplifications of the solar wind from coronal holes are expected:
on May 7, 12 - 14, (17,) 22 - 26, 31, June 1
Remark:
- Parenthesis means lower probability of activity enhancement.
