[ips-sf] ASWFC Summary Forecast for 25 September - issued 2313UT/24-Sep-2022 [SEC=OFFICIAL]

[rwc]

Solar activity is expected to be at ASWAS R1 level on 25-Sep, with
isolated low level ASWAS R class flare activity expected. The solar
wind is expected to be light to moderate on 25-Sep due to a coronal
hole wind stream, then to gradually decline. Generally G0 geomagnetic
conditions are expected, with a slight chance of G1 periods due to
coronal hole high speed wind stream effects. Mostly normal HF
propagation conditions are expected, with mild degradations possible
for middle to high latitudes during local night hours associated with
mild coronal hole high speed wind stream induced geomagnetic activity.
Isolated fadeouts impacting lower HF frequencies are possible.
