[ips-sf] SWS Summary Forecast for 09 October - issued 2323UT/08-Oct-2017 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was very low today (UT day 8 October). Solar wind
stream is expected to remain at the normal levels on 9 and 10 October
and is then expected to gain some strength from the second half of 11
November due to the effect of a positive polarity recurrent coronal
hole. Very low levels of solar activity may be expected for the next
three days (9 to 11 October). Geomagnetic conditions were at quiet
levels across the Australian region today. Mostly quiet geomagnetic
conditions may be expected for the next two days (9 to 10 October)
with the possibility of activity rising to active levels on 11
November due to the possible effect of a positive polarity recurrent
coronal hole. Some increase in geomagnetic activity to unsettled
levels may be possible on 10 October if the coronal hole effect starts
earlier than expected. MUFs were near predicted monthly values to
enhanced by 35 % during the UT day 8 October. MUFs may be expected to
stay mostly near monthly predicted values from 9 to 10 October UT
days. Minor to mild MUF depressions may be possible on 11 October due
to an expected rise in geomagnetic levels from this day.
