On UT day 25-Mar solar flare activity is expected to be R0-R1. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be moderate due to the declining influence of a coronal hole wind stream. Geomagnetic activity is expected to be G0, slight chance G1. HF radio propagation conditions are expected to be fair to normal. Maximum usable frequencies in Australian region are expected to be mildly depressed by 10-20% to near predicted monthly values.
