COMMENT: ASWFC Preliminary HF Communications Warning 53 was issued 
on 6 June and is current for 8-10 Jun. Maximum usable frequencies 
(MUFs) in the Australian region on UT day 6-Jun were mostly near 
predicted values to 15% enhanced, although conditions were degraded. 
Conditions in Darwin were degraded during local night hours, 
and spread-F and sporadic-E were present during local night hours 
in Hobart, Learmonth and Townsville. MUFs are expected to be 
near predicted values on 7-Jun to 10% depressed. MUFs are expected 
to be near predicted values for most of 8-Jun, but begin depressing 
by the end of the day and into 9-Jun by up to 20%.
