[ips-sf] SWS Summary Forecast for 19 January - issued 2326UT/18-Jan-2018 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was very low today (UT day 18 January). Very low levels
of solar activity may be expected for the next three days (19 to 21
January) with a slight chance of isolated C-class flare. Geomagnetic
activity stayed at quiet levels across the Australian region today.
Mostly quiet geomagnetic conditions are expected in this region on 19
January. Geomagnetic activity may rise to active levels on 20 and 21
January due to the effect of a coronal hole. Minor to moderate MUF
depressions were observed today. Periods of Sporadic E blanketing were
also evident. Mostly normal HF conditions may be expected on 19
January. An expected rise in geomagnetic activity from late hours on
19 January and continued very low levels of solar activity may cause
minor to significant MUF depressions on 20 and 21 January.
