[ips-sf] SWS Summary Forecast for 25 December - issued 2329UT/24-Dec-2016 [SEC=UNCLASSIFIED]

[rwc]

Solar flare activity was very low over the last 24 hours. As
anticipated, solar wind stream stayed strong due to the continued
coronal hole effect. This coronal hole effect is expected to keep the
solar wind stream strong for the next one to two days (25 and possibly
26 December). Very low levels of solar activity may be expected for
the next three days (25, 26 and 27 December). The geomagnetic activity
remained enhanced today (24 December) due to the continued effect of
the coronal hole. The enhancements were below the expected levels.
Mostly quiet to unsettled levels of geomagnetic activity with some
possibility of isolated active periods on high latitudes, may be
expected on 25 December. Geomagnetic activity is then expected to
gradually decline to quiet to unsettled levels on 26 December, and
then to mostly quiet levels on 27 December. Minor to mild depressions
in MUFs were observed today (24 December UT). Nearly similar HF
conditions may be expected on 25 December. MUFs are expected to stay
mostly near predicted monthly values on 26 and 27 December.
