Solar activity on UT day 20-Aug is expected to be at the R0 level,
with a chance of R1. S0 solar radiation storm conditions are expected.
The solar wind speed is expected to be strong. G0-G1 geomagnetic
conditions are expected due to coronal hole high speed wind stream
effects. HF radio propagation conditions are expected to be mostly
normal, with degradations expected at high latitudes. Maximum usable
frequencies (MUFs) in the Australian region are expected to be near
predicted monthly values.
