2. FORECAST (09 AUGUST - 15 AUGUST)
Solar: Very Low to Low solar activity expected for the forecast period 
with no significant returning regions.

Geomagnetic:  Possible Active conditions between 10-13 Aug due to expected
arrival 
of glancing blow CME's late in UT day on 09Aug and beginning of UT day for 11Aug

combined with recurrent coronal hole effects beginning 12Aug. Quiet to Unsettled

on other days.

Frequencies: Depressed MUF's expected for mid latitudes after local dusk 10 Aug 
through to 14Aug. Disturbed HF conditions for high latitudes for the same 
forecast period. MUFs near predicted monthly values on other days.
