2. FORECAST (03 DECEMBER - 09 DECEMBER)
Solar: Very Low to Low solar activity expected for the 
forecast period.

Geomagnetic: Mostly Quiet to Unsettled conditions, possible 
Active periods for 03Dec-05Dec due to possible CME effects and
for 08Dec-09Dec from recurrent coronal hole activity. 

Frequencies: Depressed MUFs of ~20% for low to mid latitudes
due to reduced EUV ionisation/low sunspot activity. Possible
disturbed conditions due to elevated geomagnetic activity for 
mid to high latitudes.
