level, with a chance of R1. S0 solar radiation storm conditions are
expected. The solar wind speed is expected to be strong to very
strong. G1-G2 geomagnetic conditions are expected due to ongoing
coronal hole high speed wind speed effects combined with an
anticipated glancing CME impact. HF radio propagation conditions are
expected to be mostly normal, with some mild degradations, mostly at
high latitudes. Maximum usable frequencies in the Australian region
are expected to be mostly near predicted monthly values.
