Predicted Monthly T index for January: -12

2. FORECAST (16 JANUARY - 22 JANUARY) 
MUFS: MUFs near predicted monthly values to depressed by 15 to 30% due
to very low levels of ionising radiation from the Sun.

Propagation conditions: Normal. No SWFs.

T index: -12

3. OUTLOOK (23 JANUARY - 22 FEBRUARY)
Degraded HF propagation conditions possible:
Minor to Moderate MUF depressions possible throughout this period due
to very low levels of ionising radiation from the Sun.

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.
