2. FORECAST (30 JANUARY - 05 FEBRUARY) 
MUFS: MUFs near predicted monthly values.

Minor MUF depressions are possible during this period due
to very low to low levels of solar activity.

Propagation conditions: Normal. No SWFs.

T index: 80

3. OUTLOOK (06 FEBRUARY - 08 MARCH)
Degraded HF propagation conditions possible:
No significant degraded periods expected.

Minor degradations are possible during this period due
to very low to low levels of solar activity.

PLEASE NOTE:
Space weather conditions can frequently be determined by short 
timescale events that cannot be forecast a week in advance,
particularly at solar maximum.
