[ips-sf] ASWFC Summary Forecast for 06 December - issued 2349UT/05-Dec-2023 [SEC=OFFICIAL]

[rwc]

Solar activity on UT day 06-Dec is expected to be at the R1 level,
with a slight chance of an isolated R2 flare. A new active region has
rotated onto the solar disk and is currently growing. The solar wind
speed is expected to be strong due to a coronal hole wind stream. G0
geomagnetic conditions are generally expected for 06-Dec. Geomagnetic
G1-G2 conditions are expected from the second half of UT day 07-Dec
due to a recent filament eruption/CME. HF radio communication
conditions are expected to be fair to normal today. Maximum usable
frequencies (MUFs) are expected to be generally near predicted monthly
values for the northern Australian region, with depressions of 15-20%
early in the UT day for the southern Australian region, then
recovering. Isolated minor shortwave fadeouts are probable.
