2. FORECAST (08 FEBRUARY - 14 FEBRUARY) 
MUFS: MUFs are expected to be near predicted monthly values.

Propagation conditions: Degradations are possible on 08-Feb due
to possible increased geomagnetic activity. Otherwise normal propagation
conditions expected. SWFs are possible throughout the week.

T index: 75
ASWFC HF Communications Warning 13 was issued on 7 February and 
is current for 7-8 Feb. ASWFC SWF HF Communications Warning 14

Degraded HF propagation conditions possible:
18-19 Feb, 05-06 Mar, 09-10 Mar

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.
