2. FORECAST (02 JULY - 04 JULY)
Date   T index  Conditions       MUFs                              
02 Jul    20    Poor-fair        Near predicted monthly values/depressed 
                                 15 to 25%
03 Jul    10    Poor-fair        15 to 35% below predicted monthly 
                                 values    
04 Jul    10    Poor-fair        Near predicted monthly values/depressed 
                                 15 to 35%   

COMMENT: Minor depressions to near predicted monthly values with 
periods of slightly improved ionospheric support for HF communications 
observed in the Australian region today, 1 Jul. Noted Spread 
F periods observed at Hobart and Darwin stations. An expected 
increase in geomagnetic activity associated with a coronal hole 
is likely to result in degraded HF conditions and MUF depressions 
especially in mid and high latitude regions of Australia on 2-4 
Jul.
