local night. The Southern Australian region had near predicted 
monthly values during the local day and Enhanced MUFs during 
the local night. Sporadic E was observed, mainly in the low to 
mid latitudes. For the UT day 8 May, it is expected that most 
of the Australian region will have MUFs near predicted monthly 
values, while the Northern Australian and Island regions may 
experience periods with Minor to Moderate depressions in MUFs.
