2. FORECAST (30 AUGUST - 05 SEPTEMBER)
Solar: Low to Moderate

Geomagnetic:  Mostly Quiet to Unsettled 

Frequencies:  Near predicted monthly values. SWFs possible 
              during the week.

PEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
