Solar
activity forecast for the period May 20 - May 26, 2016
Activity level: mostly very low to low
X-ray background flux (1.0-8.0 A): in the range A9.5-B4.0
Radio flux (10.7 cm): a fluctuation in the range 85-110 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 10-85

Geomagnetic activity forecast for the period May 20 - May 26, 2016
Quiet: May 23 - 26
Unsettled: May 20 - 23
Active: May 19 - 20
Minor storm: possible May 19 - 20
Major storm:0
Severe storm: 0
Geomagntic activity summary:
We expect active conditions the next two days (maximum of geomagnetic
activity is expected at May 20, but, in our longitude, the arrival of
active episode is probable today evenings. e.g. Thursday, May 19).
During the coming weekend, we expected at most unsettled conditions, then,
geomagnetic activity decrease. The second half of forecasted week, we
expect quiet to unsettled conditions return. Next active episode is
expected just in the next period (May 26 - June 2).

Geomagnetic activity forecast for the period May 20 - June 15, 2016
Geomagnetic field will be:
quiet on May 23, 26 - 27, June 9 - 10
mostly quiet on May 24, June 3, 14 - 15
quiet to unsettled on May 25, 28, June 1 - 2, 7 - 8, 11,
quiet to active on May 20 - 22, 29, 31, Jun 4 - 5, 12 - 13
active to disturbed on May 30, June 6
Amplifications of the solar wind from coronal holes are expected
on May 22 - 26, June 1 - 2, 6 - 8, 14 - 15
Remark:
- Parenthesis means lower probability of activity enhancement.
- Reliability of predictions is reduced again.
