On UT day 21-Jan solar activity is expected to be R1-R2. The solar wind speed is expected to be moderate to strong. The solar wind speed is elevated due to a coronal hole wind stream and is expected to gradually decline in coming days. G0 geomagnetic conditions are expected with a chance for G1. S0 solar radiation storm conditions are expected. HF radio propagation conditions are expected to be fair to normal with some mild degradations during local night hours and briefly after dawn. Maximum usable frequencies in the Australian region are expected to be 15% depressed to near predicted values. Isolated minor shortwave fadeouts are possible.
