[ips-sf] ASWFC Summary Forecast for 02 January - issued 1546UT/01-Jan-2025 [SEC=OFFICIAL]

[Australian Space Weather Forecasting Centre]

G3 planetary geomagnetic conditions have been observed starting at
14:00UT on 01-Jan. Australian geomagnetic conditions have reached the
G2 level. Further periods of G3 geomagnetic conditions are possible
over 01-02 Jan due to ongoing CME effects. Auroras may be sighted from
high latitude locations such as Tasmania and southern Victoria. Solar
activity on UT day 01-Jan is expected to be at R1-R2 levels, with a
chance of R3. S0 solar radiation storm conditions are expected. The
solar wind speed is expected to be moderate to strong. HF radio
propagation conditions are expected to be mostly fair to normal, with
degradations likely due to geomagnetic activity. Maximum usable
frequencies are expected to be near predicted monthly values to 15%
depressed. Shortwave fadeouts are possible.
