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

Propagation conditions: Normal propagation conditions are expected. Mild
degradations are possible at high latitudes during local night hours.
Shortwave fadeouts are possible.

T index: 118

3. OUTLOOK (17 JULY - 16 AUGUST)
No strong recurrent patterns, however mildly degraded HF propagation conditions
possible:
12-17 Jul, 8-13 Aug

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.
