COMMENT: ASWFC SWF HF Communications Warning 65 was issued on 
14 June and is current for 14-15 Jun. Maximum usable frequencies 
(MUFs) on UT day 14-Jun were mostly near predicted monthly values. 
Depressions of 15% were observed in northern Australia during 
local day. Spread-F was observed at Hobart during local night 
hours. MUFs are expected to be near predicted values over 15-17 
Jun, but may become depressed on 16-Jun due to possible anticipated 
geomagnetic activity. Shortwave fadeouts are possible.
