The Earth has entered a coronal hole wind stream earlier than expected with the solar wind speed increasing to very strong. Planetary G3 conditions were observed overnight. HF radio propagation conditions are expected to be poor to normal. Maximum usable frequencies in the Southern Australian region are expected to be depressed by up to 30%. Northern Australian region MUFs are expected to be near predicted monthly values. Isolated minor fadeouts are possible.
