COMMENT: HF conditions are expected to remain mostly normal in 
most parts of Aus/NZ regions for the next day (05 August). Onset 
of Unsettled geomagnetic activity from a recurrent coronal hole 
on 05-06 August (UT) will probably raise MUFs slightly. Strong 
nightime spread-F was observed at sub-equatorial latitudes.
