[ips-sf] SWS Summary Forecast for 23 October - issued 2359UT/22-Oct-2016 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was very low over the last 24 hours. Solar activity is
expected to stay at very low levels for the next three days (23, 24
and 25 October) with some chance of C-class activity. The effect of a
positive polarity coronal hole is expected to strengthen the solar
wind stream for the next three days. Geomagnetic activity stayed
mostly at Quiet to Unsettled levels today (UT day 22 October).
Geomagnetic activity is expected to rise from Quiet to Minor Storm
levels on 23 October due to the effect of a coronal hole. Geomagnetic
activity may stay higher at Active to Minor Storm levels on 24 October
and 25 October with some possibility of isolated major storm periods
on these days. Mainly due to low levels of ionising radiation, minor
to moderate MUF depressions were observed today (UT day 22 October).
Minor to significant MUF depressions may be expected on 23, 24 and 25
October due to very low levels of ionising radiation and expected rise
in geomagnetic activity levels on these days.
