[ips-sf] SWS Summary Forecast for 18 October - issued 2343UT/17-Oct-2016 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was low over the last 24 hours. A C4 flare was
observed. The solar wind stream is going strong due to the effect of a
coronal hole. This coronal hole effect is expected to gradually weaken
over the next 48 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 varied mostly between Quiet and Active levels
with some minor storm periods today due to the coronal hole effect.
Geomagnetic activity is expected to gradually weaken over the next 2
days. Minor to moderate MUF depressions and degradations in HF
conditions were observed today. Nearly similar HF conditions may be
expected on 18 October. Improvements to mostly normal levels are
expected in HF conditions through 19 and 20 October.
