COMMENT: ASWFC SWF HF Communications Warning 52 was issued on 
4 June and is current for 4-6 Jun. Maximum usable frequencies 
(MUFs) on UT day 5-Jun were near predicted values to 15% enhanced. 
Conditions were degraded in Darwin and Norfolk Island during 
local night hours. Spread-F was observed in Townsville and Hobart 
during local night hours. MUFs are expected to become 10-20% 
depressed over 6-7 Jun due to recent geomagnetic activity. Some 
spread-F is possible. Conditions are likely to improve by 8-Jun.
