On UT day 20-Mar solar flare activity is expected to be R0. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be initially light then becoming strong due to anticipated CME arrivals. The forecast CME arrival and subsequent geomagnetic G2 storm activity expected from late in the UT day on 19-Mar has not yet eventuated. Geomagnetic conditions are expected to be initially at G0, then increasing to G1-G2 with two CME shocks now expected to arrive on 20-Mar. HF radio propagation conditions are expected to be initially normal, becoming fair to poor late in the UT day for the southern Australian region. Maximum usable frequencies in the Australian region are expected to be mostly near predicted values, becoming 15-20% depressed late in the UT day (after local dawn 21-Mar).
