[ips-sf] SWS Summary Forecast for 25 March - issued 2317UT/24-Mar-2017 [SEC=UNCLASSIFIED]

[rwc]

Solar activity has been very low today (24 March, UT). Very Low levels
of solar activity are expected for the next 3 days (25 to 27 March)
with a slight chance of C-class activity. The effect of the solar wind
stream from the recurrent coronal hole has shown weakening through the
UT day today (24 March).Geomagnetic activity did not rise to the
expected levels as IMF Bz did not show sustained periods of negative
enough values. Geomagnetic activity may rise to active levels on 25
March, if Bz turns sufficiently southwards and for sufficiently long
intervals of time. Due to the weakening effect of the coronal hole,
geomagnetic activity is expected to gradually decrease to unsettled
and then to quiet levels through the days 26 and 27 March. MUFs were
mostly near predicted monthly values today (24 March, UT) with some
periods of minor to mild enhancements in the equatorial regions.
Nearly similar HF conditions are expected for the next three days (25
to 27 March).
