Forecast of Solar and Geomagnetic Activity
17 July - 12 August 2017

Solar activity is expected to be low with a chance for M-class flare
activity (R1-R2 / Minor-Moderate) through 19 Jul when Region 2665
exits the visible disk. Very low to low levels are expected from
20-28 Jul. A chance for R1-R2 activity is possible with the return
of old Region 2665 from 29 Jul - 12 Aug.

There is a chance for an S1 (Minor) solar radiation storm through 19
Jul due to potential significant flare activity from Region 2665. No
proton events are expected from 20-28 Jul. A chance for S1 (Minor)
solar radiation storms is possible with the return of old Region
2665 from 29 Jul - 12 Aug.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be reach high levels on 19-20 Jul due to influence from
the 14 Jul CME. Normal to moderate levels are expected for the
remainder of the outlook period.

Geomagnetic field activity is expected to be at G1-G2
(Minor-Moderate) geomagnetic storm levels on 17 Jul due to continued
CME effects. Unsettled to active levels are expected on 21-22 Jul
and again on 05-06 Aug, with G1 (Minor) geomagnetic storm levels
likely on 05 Aug, due to positive polarity CH HSS influence. Quiet
to unsettled levels are expected for the remainder of the outlook
period.
