Solar activity forecast for the period May 13 - May 19,
2016
Activity level: mostly very low to low
X-ray background flux (1.0-8.0 A): in the range A8.5-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 13 - May 19, 2016
Quiet: May 13 - 15, 18 - 19
Unsettled: May 15 - 17
Active: unlikely about May 16
Minor storm: 0
Major storm:0
Severe storm: 0
Geomagntic activity summary:
After the last active episode, solar wind velocity has again decreasing
course. During the coming weekend, we expect at most quiet conditions.
Unsettled or (unlikely) active episode is expectable between May 15 - 17.
Then, we expect turning to quiet (quiet to unsettled, respectively)
condition again. This conditons should persist to the end of forecasted
week.

Geomagnetic activity forecast for the period May 13 - June 8, 2016
Geomagnetic field will be:
quiet on May 16 - 17, 25 - 26
mostly quiet on May 15, 22 - 24, 31, June 7 - 8
quiet to unsettled on May 13 - 14, 18, 21, 27, 30
quiet to active on May 19 - 20, 28 - 29, June 1 - 2, 3, 6
active to disturbed on May (28), June 4 - 5
Amplifications of the solar wind from coronal holes are expected:
on May 19 - 21, 28 - 29, June 1 - 6
Remarks:
- Parenthesis means lower probability of activity enhancement.
