2. FORECAST (09 JULY - 15 JULY)
Solar: Very low to low.

Geomagnetic:  
Mostly quiet to unsettled.
Some active periods are likely on 12-13 July due to a large Southern Polar
coronal hole with extension down to low latitudes.

Frequencies:  
MUFs mostly near predicted monthly values.
Some mild to moderate MUF depressions may be observed on 13-15 July due to the
expected increase in geomagnetic activity.
