[ips-sf] SWS Summary Forecast for 19 October - issued 2330UT/18-Oct-2016 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was very low over the last 24 hours. The coronal hole
effect seems to have started to weaken and is expected to further
weaken over the next 24 hours. Solar activity is expected to stay at
very low levels for the next three days with some chance of C-class
activity. Geomagnetic activity stayed mostly at Quiet levels on most
locations with some Unsettled and Active periods on high latitude
locations today (UT day 18 October). Geomagnetic activity is expected
to be at Quiet to Unsettled levels on 19 October and Quiet levels on
20 and 21 October. Due to low levels of ionising radiation and
slightly enhanced geomagnetic activity levels, minor to moderate MUF
depressions and degradations in HF conditions were observed today (UT
day 18 October). Minor degradations in HF conditions and depressions
in MUFs are possible on 19 October. Improvements to mostly normal
levels are expected in HF conditions through 20 and 21 October.
