region were near predicted monthly values to 15% enhanced in 
northern Australia on UT day 16-Feb. Spread F was observed at 
Hobart during local night hours. Sporadic E was observed in southern 
Australian regions, mostly during local night hours. MUFs are 
expected to be near predicted monthly values over 17-19 Feb, 
with a chance of mild depressions in southern Australia on 17-Feb 
due to ongoing geomagnetic activity. Sporadic E is possible during 
local night hours in southern Australian regions. Shortwave fadeouts 
are possible.
