COMMENT: Variable depressions observed Equatorial/N Aus regions, 
otherwise mostly normal HF conditions observed over the past 
24 hours. Expect mildly depressed HF conditions over the next 
24-48 hours, particularly in the NZ/S.Aus/Antarctic regions in 
response to elevated geomagnetic activity levels, with variable 
depressions continuing in the Equatorial/N.Aus regions. Isolated 
disturbances possible in the Antarctic region associated with 
periods of enhanced geomagnetic activity.
