2. FORECAST (10 APRIL - 16 APRIL) 
MUFS: MUFs are expected to be near predicted monthly values in
the Australian region this week.

Propagation conditions: Mostly normal HF propagation conditions
are expected. Shortwave fadeouts are possible over 12-16 Apr due
to the anticipated return of an active sunspot region.

T index: 115

3. OUTLOOK (17 APRIL - 17 MAY)
Degraded HF propagation conditions are possible over 18-22 Apr
and 01-03 May.

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.
