2. FORECAST (18 JUNE - 24 JUNE)
Solar: Low. Regions 634 and 635 have the portential for further
C-class flare activity and possible M-class. 

Geomagnetic:  Mostly Quiet with Unsettled to Active intervals possible.

Frequencies:  Near predicted monthly values. MUFs expected to be
near normal. No SWFs.

PLEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
