[ips-sf] ASWFC Summary Forecast for 12 June - issued 2311UT/11-Jun-2023 [SEC=OFFICIAL]

[rwc]

Solar activity on UT day 12-Jun is expected to be R0, with the slight
chance of isolated R1 flare activity. The solar wind speed is expected
to be initially moderate declining to light as recent mild coronal
hole wind stream influences abate. The moderate increase in solar wind
speed only very mildly increased geomagnetic activity during the first
half of 11-Jun. Geomagnetic activity is expected to be G0. Maximum
usable frequencies (MUFs) are expected to remain near predicted
values. HF communication conditions are expected to be normal to fair,
with possible mild degradations during local night hours.
