2. FORECAST (29 AUGUST - 04 SEPTEMBER)
Solar:        Low. M-class activity possible from returning 
	      activie region.

Geomagnetic:  Mostly Quiet to Unsettled with Active to Minor storm 
	      intervals possible, especially mid-week.

Frequencies:  Mildy depressed after local dawn on 02-Sep, depressed 
	      15% 03-04 Sep, otherwise MUFs near normal. No SWFs.

PLEASE 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.
