2. FORECAST (01 JULY - 07 JULY)
Solar: Very Low to Low solar activty expected. 

Geomagnetic: Unsettled conditions with possible Active 
periods for high latitudes expected for 02Jul-03Jul due to
recurrent coronal hole effects, otherwise mostly 
Quiet conditions.

Frequencies: Variable MUF depressions of ~20% for mid to low 
latitudes for the forecast week due to increased geomagnetic
activity and low solar activity. Disturbed conditions for 
high latitudes.
