[ips-sf] IPS Summary Forecast for 22 May - issued 2345UT/21-May-2016 [SEC=UNCLASSIFIED]

[rwc]

Solar X-ray flare activity was low during 21 May UT and it is expected
to be low today, 22 May. Active Region 2546 is the largest visible
sunspot group and has increased in magnetic complexity. It will
probably produce another weak C class flare during the next 2 days.
There is a small chance that it will produce an M class flare before
rotating off the visible disk later this week. No major solar wind
disturbances are expected to arrive at Earth during the next 2 days.
Under the influence of a coronal hole, the solar wind speed slowly
increased to 600 km/s during 21 May. Geomagnetic conditions briefly
reached minor storm levels (Kp=5) during 06-09 UT. They are expected
to be unsettled to active today, 22 May UT, decreasing to quiet to
unsettled during 23 May. Conditions for HF radio wave propagation are
expected to be mildly depressed today.
