[ips-sf] SWS Summary Forecast for 27 March - issued 2318UT/26-Mar-2017 [SEC=UNCLASSIFIED]

[rwc]

Solar activity has been very low today (26 March, UT). The effect of a
recurrent coronal hole is expected to strengthen the solar wind stream
from 27 March. Very Low levels of solar activity are expected for the
next 3 days (27 to 29 March) with a slight chance of C-class activity.
Geomagnetic activity stayed at quiet levels in the Aus/NZ regions
today. Due to the effect of a recurrent negative polarity coronal
hole, geomagnetic activity is expected to rise up to active levels
with some possibility of minor storm conditions on 27 March (UT).
Unsettled to minor storm levels of activity are expected on 28 and 29
March with the possibility of some major storm periods on these days.
MUFs were mostly near predicted monthly values today with some periods
of minor to mild depressions in the mid latitude regions. Due to
expected rise in geomagnetic activity levels from 27 March, minor to
mild MUF depressions and degradations in HF conditions are possible on
this day. Minor to moderate MUF depressions and degradations in HF
conditions are likely on 28 and 29 March.
