MUFS: MUFs near predicted monthly values.
Propagation conditions: Normal. No SWFs
T index:   3

3. OUTLOOK (11 MARCH - 10 APRIL)
Degraded HF propagation conditions possible:
No signficant degraded periods expected. Moderate MUF depressions
and enhancements possible at times due to continuing low solar
activity, especially Equatorial/N Aus regions.

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.
