[ips-sf] SWS Summary Forecast for 24 February - issued 2336UT/23-Feb-2017 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was low on UT day 23 February. Region 2638 (N18E20)
produced a C1.3 flare that peaked at 2053 UT. The previously
anticipated coronal hole effect has started and it is expected to keep
the solar wind stream stronger on 24 and 25 February. Very low levels
of solar activity may be expected for the next 3 days (24-26 February)
with a slight chance of C-class activity. Geomagnetic activity was at
quiet to unsettled levels across the Australian region on UT day 23
February. It was below the anticipated levels as Bz did not show
sustained periods of sufficiently negative values. Geomagnetic
activity may rise up to active levels on 24 and 25 February with some
possibility of minor storm periods on 24 February. MUFs were mostly
near predicted monthly values during UT day 23 February. Minor to
moderate MUF depressions and degradations in HF conditions may be
expected from 24 to 25 February due to expected rises in geomagnetic
activity levels on these days.
