[ips-sf] ASWFC Summary Forecast for 23 January - issued 2310UT/22-Jan-2023 [SEC=OFFICIAL]

[rwc]

Solar activity on UT day 23-Jan is expected to be at the R1 level. The
solar wind speed is expected to be moderate, with the chance of an
increase late in the UT-day. G0 geomagnetic conditions are expected,
with a chance of G1 due to the combined effects of possible glancing
blows from CMEs first observed on 19-Jan and 20-Jan, and high speed
wind stream effects from an equatorial coronal hole, which is rotating
towards a geoeffective position. Australian region maximum usable
frequencies are expected to be near predicted monthly values to 15%
enhanced, with more significant enhancements expected for the Northern
Australian region. Shortwave fadeouts are possible.
