COMMENT: ASWFC SWF HF Communications Warning 61 was issued on 
7 June and is current for 7-9 Jun. Maximum usable frequencies 
(MUFs) in the Australian region on UT day 07-Jun were near predicted 
monthly values. Spread-F was observed in Townsville and Hobart 
during local night hours. MUFs are expected to be generally near 
predicted values over 08-10, however may experience mild depressions 
in the following day due to recent geomagnetic activity.
