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.

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.
