2. FORECAST (02 JULY - 04 JULY)
Date   T index  Conditions       MUFs                              
02 Jul    45    Normal           Near predicted monthly values
03 Jul    45    Normal-fair      Near predicted monthly values    
04 Jul    45    Normal           Near predicted monthly values   

COMMENT: Maximum usable frequencies (MUFs) on UT day 01-Jul were 
variable with MUFs near monthly predicted values to up to 25% 
depressed at times. Spread F was observed during local night 
hours, implying degraded overnight HF communications conditions. 
MUFs are generally expected to be near predicted monthly values, 
with degraded conditions possible 03-04 Jul in association with 
the chance of an increase in geomagnetic activity induced from 
recent CMEs.
