COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
region were near predicted monthly values over UT day 02-Jul, 
with enhancements of up to 20% observed in the southern Australian 
region, as well as at Niue Island and in the Antarctic region. 
Significant spread-F was observed at sites on the east coast 
of Australia. MUFs are forecast to become depressed over 03-Jul 
due to forecast geomagnetic activity, with 15-20% depressions 
forecast. Mild depressions are expected over 04-05 Jul as this 
geomagnetic activity continues. Shortwave fadeouts are probable.
