COMMENT: MUFs were near predicted monthly values on average at 
most locations during daylight hours over the last 24 hours with 
the daily T index only slightly below the predicted monthly average. 
However night-time MUFs were depressed, particularly across low 
latitudes. Expect mostly normal HF conditions next two days, 
with MUFs perhaps slightly below average. There may be moderate 
geomagnetic activity on the 3rd day 25-Jul causing larger hourly 
MUF variations.
