[ips-sf] SWS Summary Forecast for 18 December - issued 0103UT/18-Dec-2017 [SEC=UNCLASSIFIED]

[rwc]

Very low levels of solar activity is expected for today, 18 December.
The earth is currently under the influence of moderately elevated
solar winds emanating from equatorial coronal hole. As a result, the
geomagnetic conditions are expected to be between quiet to active
levels, and at times may reach minor storm levels today.
High-frequency radio communication users are advised to use slightly
lower than the monthly predicted frequencies, today. The CME
associated with the erupting filament that occurred around 15/1100 UT
from the southeast solar quadrant is not likely to impact earth.
