COMMENT: Australian Region MUFs were genrally returning to normal 
over the last 24h. Equatorial regions still show large enhancements 
and depressions about the avergae however. A significant depletion-enhancement-depletion 
was observed at most stations across the region just after dusk. 
More prominent at equatorial latitudes and also occurring in 
the east (Niue) earlier, suggesting a wave trailing the dusk 
terminator. Some strong spread-F was observed in equatorial regions 
(Vanimo at night) and in the south-east (Hobart pre-dawn and 
Christchurch at night). For more detail on particular regions 
and times go to "www.ips.gov.au/HF_Systems/1/3" to view the ionograms.
