On UT day 15-Jun solar activity is expected to be R1, chance R2. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be moderate to strong due to a coronal hole wind stream. G0-G1 geomagnetic conditions are expected. HF radio propagation conditions are expected to be fair. Maximum usable frequencies in the Australian region are expected to be initially 15-25% depressed, gradually recovering today. Brief isolated minor shortwave fadeouts are possible.
