[ips-sf] SWS Summary Forecast for 28 February - issued 2335UT/27-Feb-2017 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was at very low levels during the UT day 27 February.
The largest observed flare, B9.3, was produced by a new active region
2641. Very low to low levels of solar activity are expected for the
next 3 UT days. A negative polarity recurrent coronal hole has started
strengthening the solar wind stream. The solar wind speed has already
reached moderate values and is expected to increase further.
Geomagnetic activity was at quiet levels across the Australian region
on UT day 27 February. Nearly similar levels of geomagnetic activity
are expected for the first half of 28 February. Activity is then
expected to gradually increase to unsettled and active levels due to
the coronal hole effect. This effect may keep the geomagnetic activity
enhanced to unsettled to active levels with the possibility of some
minor storm periods on 1 March. MUFs were mostly near predicted
monthly values during UT day 27 February. Nearly similar HF conditions
may be expected for early parts of 28 February. Minor to mild MUF
depressions and degradations in HF conditions are expected late on 28
February. Minor to moderate MUF depressions and degradations in HF
conditions are likely on 01 March.
