2. FORECAST (11 JUNE - 17 JUNE)
Solar: Very low to low.

Geomagnetic:  
Unsettled to active conditions 15-17 June due to a Southern Polar coronal hole
with extensions down to low latitudes.
Mostly quiet otherwise. 

Frequencies:  
Some mild MUF depressions are possible 16-17 June due to the expected increase
in geomagnetic activity.
MUFs mostly near predicted monthly values otherwise.
