On UT day 13-Jul 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 to normal, with fair conditions during local night hours. Maximum usable frequencies in the Australian region are expected to be 15-20% depressed to near predicted values. Isolated minor shortwave fadeouts are possible.
