[ips-sf] ASWFC Summary Forecast for 30 June - issued 2318UT/29-Jun-2023 [SEC=OFFICIAL]

[rwc]

Solar activity on UT day 30-Jun is expected to be at the R1 level,
with a chance of an isolated R2 flare. A moderately large solar region
is currently just west of the centre of the solar disk. This region
has yet to produce a significant solar flare. The solar wind speed is
expected to be initially moderate then declining to light, with a weak
increase in the solar wind speed possible on 01-Jul due to a recent
minor CME. G0 geomagnetic conditions are expected. Maximum usable
frequencies (MUFs) are expected to be near predicted monthly values to
15% enhanced. HF communication conditions are expected to be mostly
normal during local day, with mildly degraded conditions possible
during local night hours. Shortwave fadeouts are possible.
