Predicted Monthly T index for October:  60

2. FORECAST (07 OCTOBER - 13 OCTOBER) 
MUFS: 
Maximum usable frequencies in the Australian region are
expected to be near predicted monthly values to depressed
by up to 15% over 09-11 Oct and near predicted monthly
values over 07-08 and 12-13 Oct. Expected depressed 
conditions are due to anticipated geomagnetic activity.

Propagation conditions: 
Propagation conditions are expected to be fair to poor
over 09-11 Oct and normal on all other days.

Minor shortwave fadeouts are possible over the week.

T index: 60

3. OUTLOOK (14 OCTOBER - 13 NOVEMBER)
Degraded HF propagation conditions possible:
 14-15 Oct, 21-24 Oct, 31-Oct to 02-Nov, 08-11 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.
