2. FORECAST (26 JULY - 28 JULY)
Date   T index  Conditions       MUFs                              
26 Jul    55    Fair             Near predicted monthly values/depressed 
                                 0 to 20%

28 Jul    70    Normal           Near predicted monthly values   

COMMENT: MUFs were slightly below monthly values for 24 hour 
averages across the region over the last 24 hours. However there 
was significant hourly variability with night-time MUFs depressed 
across all regions 15-35%. Over 26-27 July There will be Unsettled-Active 
geomagnetic activity due to high solar wind speed from a recurrent 
coronal hole CH576, probably causing MUF depressions up to 20% 
and larger hourly MUF variations than normal.
