16 Feb    50    Normal           Near predicted values with depressions

COMMENT: MUFs were mostly near monthly predicted values over 
the last 24 hours with daytime depressions in southern Australian 
stations of up to 20%. Significant blanketing E is currently 
being observed on east coast stations. Conditions for southern 
regions are expected to worsen over the next 24 hours due to 
sustained low level geomagnetic activity with depressions of 
at most 30% expected. Central and northern regions are expected 
to remain around predicted monthly values, with the possibility 
of mildly depressed periods for central regions. IPS HF warning 
12/09 has been issued to alert users of these conditions.
