2. FORECAST (01 JULY - 07 JULY)
Solar: Conditions are expected to be Low, with the
current regions on disk only exhibiting minor growth
in sunspot area.

Geomagnetic:  Unsettled to Active conditions for
01Jul-03Jul, with possible isolated Minor Storm periods  
due to coronal hole effects. Quiet to Unsettled on
other days.

Frequencies:  Briefly depressed after local dawn
02Jul to 04Jul. MUFs near predicted monthly values
on other days. No SWF's expected.

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.
