COMMENT: On UT day 09 Aug, depressed MUFs were observed over 
the Northern Australian region around midday. At other times, 
MUFs over Australasia were mostly near the monthly predicted 
values. Incidence of sporadic-E were observed at some low latitude 
Australian stations. The two day outlook (UT day 10-11 Aug) is 
for MUFs to trend mostly near monthly predicted levels. MUFs 
are expected to be strongest on UT day 11 August, but still near 
monthly predicted levels. Improvement in MUFs are expected at 
the onset of geomagnetic disturbance during this time of the 
year.
