Predicted Monthly T index for November:  58

2. FORECAST (04 NOVEMBER - 10 NOVEMBER) 
MUFS: Maximum useable frequencies (MUFs) in the Australian region
are expected to be near predicted monthly values over 04-06 Nov.
Depressions of 15% are possible over 07-08 Nov due to forecast geomagnetic
activity associated with a coronal hole high-speed wind stream. MUFs
are forecast to recover to near predicted monthly values over 09-10
Nov. 

Propagation conditions: Mostly normal propagation conditions are expected,
with fair conditions over 07-08 Nov.

T index: 50

3. OUTLOOK (11 NOVEMBER - 11 DECEMBER)
Degraded HF propagation conditions possible:
17-18 Nov,  27-28 Nov

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.
