COMMENT: Conditions for HF radio wave propagation were mildly 
depressed throughout the Australian region during 13 July. This 
was partly due to the negative ionospheric storm following the 
minor geomagnetic storm which occurred on 12 July. Conditions 
are expected to be mildly depressed to near normal today, 14 
July. An ionospheric trough occurred above Hobart early this 
morning.
