[ips-sf] ASWFC Summary Forecast for 25 January - issued 2315UT/24-Jan-2025 [SEC=OFFICIAL]

[Australian Space Weather Forecasting Centre]

On UT day 25-Jan solar activity is expected to be R0-R1. A glancing
blow CME arrival forecast for 24-Jan appears to have missed the Earth.
G1-G2 geomagnetic conditions are expected on 25-Jan due to another
anticipated CME arrival. S0 solar radiation storm conditions are
expected. HF radio propagation conditions are expected to be initially
normal then becoming fair to poor for middle to high latitudes.
Maximum usable frequencies in the Australian region are expected to be
initially near predicted values for most of the UT day 25-Jan then
becoming 10-20% depressed on 26-Jan. Isolated minor shortwave fadeouts
are possible. There is a chance that aurora may be observed in high
latitude locations late on UT day 25-Jan.
