[ips-sf] ASWFC Summary Forecast for 09 August - issued 2327UT/08-Aug-2025 [SEC=OFFICIAL]

[Australian Space Weather Forecasting Centre]

Solar activity on UT day 09-Aug 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 strong. G0-G1 geomagnetic
conditions are expected due to the combined effects of a southern
hemisphere coronal hole and ongoing CME arrival effects. HF radio
propagation conditions are expected to be mostly normal, with the
chance of mild degradations at high latitudes. Maximum usable
frequencies (MUFs) in the Australian region are expected to be near
predicted monthly values with the chance of mild depressions in the
southern Australian region. Shortwave fadeouts are possible.
