COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
region were mostly near predicted monthly values on UT day 15-Feb. 
Depressions of up to 15% were observed in the southern Australian 
region during local night due to recent geomagnetic activity. 
Spread F was observed at Hobart during local night hours. Sporadic 
E was observed in the southern Australian region, mostly during 
local night hours. MUFs are expected to be near predicted monthly 
values over 16-18 Feb, with a chance of mild depressions in the 
southern Australian region on 16-Feb due to recent geomagnetic 
activity. Sporadic E is likely during local night hours in the 
southern Australian region.
