2. FORECAST (18 JUNE - 24 JUNE)
Solar: Very Low to Low solar activity expected for the 
next 7 days. 

Geomagnetic:  Mostly Quiet to Unsettled conditions. 

Frequencies:  MUF's expected to be near predicted monthly 
values with depressions of 10%-20% expected for Northern 
AUS/Equatorial regions and possibly for Southern AUS/NZ 
regions due to reduced EUV ionisation/weak sunspot
activity. Periods of disturbed propgation conditions for 
Antarctic regions.
