[ips-sf] SWS Summary Forecast for 19 December - issued 2349UT/18-Dec-2017 [SEC=UNCLASSIFIED]

[rwc]

Very low levels of solar activity are expected for today, 19 December.
The earth is currently under the influence of moderately elevated
solar winds emanating from a recurrent equatorial positive polarity
coronal hole. As a result, the geomagnetic conditions are expected to
be at Quiet to Unsettled levels, and at times may reach Active levels
today. High-frequency radio communication users are advised to use
slightly lower than the monthly predicted frequencies, today.
