COMMENT: ASWFC SWF HF Communications Warning 61 was issued on 
3 July and is current for 3-4 Jul. ASWFC HF Communications Warning 
62 was issued on 3 July and is current for 3-4 Jul. Maximum usable 
frequencies (MUFs) in the Australian region on UT day 3-Jul were 
depressed up to 20%, particularly by local dawn hours. HF radio 
propagation conditions in most Australian conditions became degraded 
by late in the day into local dawn hours. Ionospheric scintillation 
was observed at Niue Island from 0911 to 0930 UT. Degraded conditions 
are likely to carry into 4-Jul and continue into 5-Jul. Conditions 
may begin to improve by 6-Jul.
