2. FORECAST (14 JUNE - 20 JUNE)
Solar: low to moderate, a returning solar region may
       bring about an increase in flare activity 
       as the week progresses.

Geomagnetic:  Mostly Quiet to Unsettled with active intervals 
       possible 15 Jun.

Frequencies:  MUFs near normal. SWFs possible later in week.

PEASE 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.
