Casey, Townsville, Vanimo, as well as Cocos and Norfolk Island 
ionograms showed ocassional sporadic E. Brisbane, Niue, and Macquarie 
Island showed sporadic E blanketing, particularly in the local 
night early morning hours. Sydney and Canberra showed sporadic 
E blacketing particularly late in the local day time hours. Noted 
strong spread F conditions at Mawson, mostly early in the local 
day. Expect similar condition to prevail for the next three days 
with mild depressions to continue in the low to mid latitudes 
due to very low solar activity.
