2. FORECAST (28 FEBRUARY - 02 MARCH)
Date   T index  Conditions       MUFs                              
28 Feb   -15    Normal           near predicted monthly values/depressed 
                                 10 to 20% 
01 Mar   -15    Normal           near predicted monthly values/depressed 
                                 10 to 20%     
02 Mar   -15    Normal           near predicted monthly values/depressed 
                                 10 to 20%    

COMMENT: Mostly normal HF conditions in the Aus/NZ region over 
the last 24 hours. Degraded HF conditions were observed at higher 
latitude sites (Hobart, south) in response to increased geomagnetic 
activity. The geomagnetic activity provided a small boost to 
MUFs bringing them back to monthly average values for the day. 
The equatorial regions saw some large fluctuation in MUFs over 
the day with enhancements and depressions of up to 30%. MUFs 
are expected to return to mildly depressed (10 to 20%) levels 
next three days due to continuing low solar activity. 28 Feb 
should see continuing MUF variability at equatorial sites, and 
degraded HF at high latitudes.
