2. FORECAST (15 JANUARY - 21 JANUARY) 
MUFS: MUFs near predicted monthly values to 15% depressed
for most of the week. 

Propagation conditions: Normal. Chance of mildly degraded 
conditions due to coronal hole activity most of the week. 
SWFs probable early in week.

T index: 119

3. OUTLOOK (22 JANUARY - 21 FEBRUARY)
Degraded HF propagation conditions possible:
Mildly degraded conditions possible over 11-13 Feb.

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.
