Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No
significant transient or recurrent solar wind features are forecast.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-13 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Aug 22-Aug 24 2017

              Aug 22  Aug 23  Aug 24
S1 or greater    1%      1%      1%

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Aug 22-Aug 24 2017

              Aug 22        Aug 23        Aug 24
R1-R2           25%           25%           25%
R3 or greater    1%            1%            1%

Rationale: There is a chance for R1-R2/Minor-Moderate radio blackouts
for the next three days (22-24 Aug) as Regions 2671 and 2672 maintain
enhanced magnetic complexities.
