FORECAST (10 JUNE - 16 JUNE) MUFS: MUFs may be depressed, particularly at high latitudes over 11-13 Jun due to anticipated geomagnetic storm activity caused by an equatorial coronal hole. Spread F is expected during local night hours in the southern Australian region. Propagation conditions: Propagation conditions are expected to be generally normal throughout the week, with degraded conditions possible at high latitudes in the northern hemisphere. More degradations are expected over 11-13 June due to anticipated geomagnetic storm activity caused by an equatorial coronal hole. T index: 68 ASWFC Preliminary HF Communications Warning 53 was issued on 6 June and is current for 8-10 Jun. 3. OUTLOOK (17 JUNE - 17 JULY) Degraded HF propagation conditions possible: 9-10 Jul 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.
