Predicted Monthly T index for September: 62 2. FORECAST (16 SEPTEMBER - 22 SEPTEMBER) MUFS: Maximum usable frequencies are expected to be near predicted monthly values to depressed by up to 15% over 16-17 Sep due to anticipated geomagnetic activity. Depressions are expected to be stronger in the southern Australian region. MUFs are expected to recover towards predicted monthly values over 18-22 Sep. Propagation conditions: HF radio propagation conditions are expected to be degraded over 16-17 Sep, primarily at higher latitudes and in the northern hemisphere due to anticipated geomagnetic activity. Conditions are expected to trend towards normal conditions over 18-22 Sep. Short wave fadeouts are not expected over 16-22 Sep. T index: 62 3. OUTLOOK (23 SEPTEMBER - 23 OCTOBER) Degraded HF propagation conditions possible: 25-27 Sep, 04-06 Oct and 12-14 Oct 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.
