[ips-sf] ASWFC Summary Forecast for 01 June - issued 0754UT/01-Jun-2025 [SEC=OFFICIAL]

[Australian Space Weather Forecasting Centre]

01/0752 Solar activity on UT day 01-Jun is expected to be at R1-R2
levels. S2 solar radiation storm conditions are expected. The solar
wind speed is expected to be very strong. An anticipated CME impact
has been observed earlier than expected and produced G3 geomagnetic
conditions at the planetary level and G1 geomagnetic conditions in the
Australian region. Further periods of planetary G3 conditions are
expected, with a chance of G4. HF radio propagation conditions are
expected to be mostly fair to poor. Maximum usable frequencies (MUFs)
in the Australian region are expected to be near predicted monthly
values to 15% depressed. Shortwave fadeouts are probable.
