[ips-sf] ASWFC Summary Forecast for 01 December - issued 2312UT/30-Nov-2023 [SEC=OFFICIAL]

[rwc]

On UT day 01-Dec solar activity is expected to be mostly R0-R1, with
the chance of an isolated R2 flare. No CME signatures have been
observed in the solar wind data over the past 24 hours, with earlier
partially Earth directed CMEs appearing to have now missed the Earth.
The recent halo R2/CME remains expected to arrive though later than
initially expected. The solar wind parameters are now expected to
become moderately enhanced from mid to late 01-Dec and into 02-Dec. G0
geomagnetic conditions are now initially expected on 01-Dec,
increasing to G2, with a chance of G3 conditions from mid 01-Dec to
02-Dec. HF radio communication conditions are expected to be initially
normal on 01-Dec, becoming moderately degraded mid to late 01-Dec.
Maximum usable frequencies (MUFs) are expected to be initially near
predicted monthly values to 15% enhanced on 01-Dec, before becoming
depressed 20% from late in the UT day on 01-Dec. Visible auroras may
be possible in middle to high latitude regions on 01-Dec.
