2. FORECAST (23 MARCH - 29 MARCH) 
MUFS: MUFs expected to be near predicted monthly values with 
enhanced MUFs ~20% for Equatorial and some Northern AUS 
regions. 

Propagation conditions: Mostly normal conditions expected 
with possible degraded conditions for 29Mar due to recurrent 
coronal hole activity. Chance of SWF's with an expected 
increase in solar activity for the forecast week.

T index:  40

3. OUTLOOK (30 MARCH - 29 APRIL)
Degraded HF propagation conditions possible:
06Apr-08Apr, 26Apr.

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.
