[ips-sf] SWS Summary Forecast for 27 December - issued 2340UT/26-Dec-2016 [SEC=UNCLASSIFIED]

[rwc]

Very low solar flare activity is expected for today, 27 December. The
Earth is currently under the influence of moderate to strong solar
wind streams from a positive polarity coronal hole. However, the solar
wind speeds are expected to decline from today as the coronal hole
effects wane. Mostly quiet to active geomagnetic conditions are
expected for today. High-frequency radio communications users are
advised to continue to use lower than the monthly predicted
frequencies due to loss in ionisation associated with the 26 December
disturbed geomagnetic conditions.
