Solar activity on UT day 01-May is expected to be at the R1 level, with a chance of R2. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be moderate. G0 geomagnetic conditions are expected, with a chance of G1 due to coronal hole high speed wind stream effects. HF radio propagation conditions are expected to be mostly normal. Maximum useable frequencies (MUFs) in the Australian region are expected to be near predicted monthly values. Shortwave fadeouts are possible.
