2. FORECAST (10 SEPTEMBER - 16 SEPTEMBER) 
MUFS: mostly near predicted monthly values.

Propagation conditions: Mostly normal. Chance for fair 
conditions 10-11 Sep, and fair condtions may also be 
experienced 14-15 Sep.

T index:   70

COMMENT: Chance for mild degradation in HF conditions 
on 10-11 Sep due to coronal hole high speed wind stream.
Effects expected to be confined to southern Aus/NZ region
(mid to high latitudes), mostly during local night hours.

3. OUTLOOK (17 SEPTEMBER - 17 OCTOBER)
Mild/moderately degraded HF propagation conditions possible
(southern Australian/New Zealand region):
14-15 Sep, 17-Sep to 20-Sep

PLEASE NOTE:
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
