2. FORECAST (04 JULY - 10 JULY)
Solar: 
Very low.

Geomagnetic:  
Mostly quiet throughout this period with some possibility of 
isolated unsettled periods on 04 July.

Frequencies:  
MUFs mostly near predicted monthly values. Periods of minor to
mild depressions in MUFs possible due to weak ionosphere.
