Date   T index  Conditions       MUFs                              
07 Aug     0    Normal           Near predicted monthly values

COMMENT: On UT day 06 Aug, moderate to severely depressed MUFs 
were observed over the Northern Australian and Antarctic regions 
around midday. At other times, MUFs over Australasia were mostly 
near the monthly predicted values. The depressed conditions are 
due to very low solar ionizing flux. The two day outlook (UT 
day 07-08 Aug) is for the MUFs to generally trend at near monthly 
predicted values.
