COMMENT: MUFs were mainly near predicted monthly values in the 
Southern Australian region during the UT day 5 March. There were 
Moderate depressions in MUFs in the Northern Australian and Niue 
Island Regions during the local day and Minor depressions during 
the local night in the Niue Island Region. There were also isolated 
cases of Sporadic E blanketing over Australian ionosonde sites. 
MUFs are expected to be mainly near predicted monthly values 
across the Australian region on 6-7 March, with the chance of 
periods of Minor depressions. MUFs may experience Minor to Moderate 
depressions on 8 March due to possible geomagnetic activity forecast 
to start on 7 March.
