2. FORECAST (04 JANUARY - 10 JANUARY)
Solar: 
Very Low to Low solar activity is expected.

Geomagnetic:  
Mostly Quiet conditions expected with possible Unsettled

Maximum MUF depressions of 20% expected for most regions, 
with continued Fair-Normal HF conditions for the forecast
period. Possible disturbed ionospheric conditions for mid 
to high latitudes during first half of the week. No SWF's
expected.
