[ips-sf] SWS Summary Forecast for 20 July - issued 2323UT/19-Jul-2022 [SEC=OFFICIAL]

[rwc]

Solar activity is expected to be at R0-R1 levels on UT day 20-Jul. The
solar wind speed is expected to be moderate to light. G0 geomagnetic
conditions are expected, with a slight chance of G1 due to the ongoing
effects of a CME impact, from a CME first observed on 15-Jul. HF radio
propagation conditions are expected to be mostly normal, with
degradations possible for middle to high latitudes. Shortwave fadeouts
are possible. Two coronal holes are currently crossing the central
meridian and are expected to influence the solar wind speed in the
coming days, with a chance of G1 geomagnetic conditions from 22-Jul.
