2. FORECAST (10 DECEMBER - 16 DECEMBER)
Solar: Very Low activity expected. No sunspots currently on the 
visible solar disc.

Geomagnetic:  Quiet to Unsettled conditions expected for 
the forecast week with possible Isolated Active periods for 
10Dec-12Dec due to CME effects.  

Frequencies:  MUFs near predicted monthly values to depressed by 25%
for Southern AUS/NZ and Antarctic regions due to low levels of EUV 
ionisation and possible elevated geomagnetic activity early in the 
forecast week.
