Date   T index  Conditions       MUFs                              
25 Jul    55    Normal           Depressed 15%/near predicted

COMMENT: HF conditions were mostly normal 24 Jul. MUFs were generally 
depressed to 25% during the local day and near predicted monthly 
values during the local night. Large variability was observed 
in the equatorial regions. Ongoing mild MUF depressions are expected 
next three days. Degraded HF conditions expected at high latitudes 
25 Jul. Solar proton flux remains mildly enhanced so weak Polar 
Cap Absorption (PCA) may be expected in the high latitude regions.
