Predicted Monthly T index for October:  60

2. FORECAST (14 OCTOBER - 20 OCTOBER) 
MUFS: Maximum Usable Frequencies in the Australian region are 
expected to be near predicted monthly values throughout the week
14-20 October, with possible mild depressions over 14-15 Oct due
to coronal hole high speed wind stream effects.

Propagation conditions: 
HF radio propagation conditions are expected to be mostly normal
on all days this week. Mild degradations may occur at high 
latitudes on 14-15 Oct due to ongoing mild geomagnetic activity.

Short wave fadeouts are not expected over 14-20 Oct.
T index: 60

3. OUTLOOK (21 OCTOBER - 20 NOVEMBER)
Degraded HF propagation conditions possible:
21-24 Oct,  31-Oct to 01-Nov, 07-10 Nov, 17-18 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.
