COMMENT: On UT day 11 April MUFs were mostly near predicted monthly 
values over the Aus/NZ region. There were a few cases of Sporadic 
E blanketing over the Australian Ionosonde sites. The three day 
outlook (12-14 April) is for MUFs to be mostly near predicted 
monthly levels. Mild depressions are likely on 12 April during 
local day in response to the recent increase in geomagnetic activity.
