Forecast of Solar and Geomagnetic Activity
24 July - 19 August 2017

Solar activity is expected to be low with a chance for M-class flare
activity (R1-R2/Minor-Moderate) on 30 Jul - 12 Aug due to the return
of old Region 2665 (S06, L=115) as it rotates through the visible
disk. Very low activity is expected for the remainder of the outlook
period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to range from normal to high levels. The influence of
recurrent, positive polarity CH HSSs are expected to cause high
levels from 24-29 Jul and again on 18-19 Aug. Moderate levels are
expected on 30-31 Jul and the remainder of the outlook period is
likely to be at normal levels.

Geomagnetic field activity is expected to range from quiet to G1
(Minor) geomagnetic storm levels. Quiet to G1 (Minor) storm levels
are likely on 05 Aug; quiet to active levels are likely on 24 Jul
and 17-18 Aug; quiet to unsettled levels are likely on 06-07 Aug and
19 Aug. All enhancements in geomagnetic activity are due to the
influence of multiple, recurrent, positive polarity CH HSSs. The
remainder of the outlook period is expected to be quiet under a
nominal solar wind regime.
