[ips-sf] ASWFC Summary Forecast for 11 January - issued 2329UT/10-Jan-2023 [SEC=OFFICIAL]

[rwc]

A short duration R3 (X1) flare was observed at 10/2247UT, with an
associated HF fadeout impacting lower HF frequencies for east coast
Australia 10/2245-2300UT. Solar activity on UT day 11-Jan is expected
to be at R1-R2 levels, with the chance of further isolated R3 events.
There are currently four solar regions capable of producing R1-R2
flares. The solar wind speed is expected to be light, with slightly
elevated solar wind speed conditions due to a weak coronal hole wind
stream. G0 geomagnetic conditions are expected. Australian region
maximum usable frequencies are expected to be near predicted monthly
values to 15% enhanced. Shortwave fadeouts are probable.
