COMMENT: Maximum usable frequencies (MUFs) on UT day 03-Jun were 
mostly near monthly predicted values, with slight depressions 
observed during local night hours for Northern Australian regions. 
Spread-F was observed during local night hours at Perth, Brisbane, 
Norfolk Island and Hobart. MUFs are expected to be mostly near 
monthly predicted values over 04-06 Jun for Northern Australian 
regions, to slightly depressed during local night hours. Mildly 
depressed and degraded conditions are expected for Southern Australian 
and Antarctic regions over 05-06 Jun due to an anticipated increase 
in geomagnetic activity from a CME first observed on 02-Jun.
