[ips-sf] ASWFC Summary Forecast for 01 April - issued 2321UT/31-Mar-2026 [SEC=OFFICIAL]

[Australian Space Weather Forecasting Centre]

On UT day 01-Apr solar flare activity is expected to be R1-R2. The
solar wind speed is expected to be moderate to very strong. G2-G3
geomagnetic conditions are expected due to the arrival of a CME. This
was estimated to arrive at approximately 31/1600UT +/- 10 hours, but
has yet to do so. Arrival is now expected during the 01-Apr. HF radio
propagation conditions are expected to be poor, as ionospheric
disturbances begin following the arrival of the CME. Maximum usable
frequencies in the Australian region are expected to be up to 30%
depressed. S0 solar radiation storm conditions are expected. Isolated
fadeouts are possible, due to flaring activity.
