2. FORECAST (29 JULY - 31 JULY)
Date   T index  Conditions       MUFs

31 Jul    70    Normal           Near predicted monthly values   

COMMENT: The regionally averaged MUFs were somewhat depressed 
over 28-Jul, particularly at night. This would be partially due 
to the weekend coronal hole geomagnetic disturbance and partly 
due to the small number of sunspots and ionising EUV to aid recovery. 
Expect MUFs to recover to near monthly overages over 29-30 Jul.
