[ips-sf] SWS Summary Forecast for 23 March - issued 2329UT/22-Mar-2019 [SEC=UNCLASSIFIED]

[rwc]

Low solar activity is expected for UT day 22 March with a chance that
the active region 2736 will produce an isolated M-class flare. Up to
arrival of the CME which became visible on 20 March at 1140 UT, the
solar wind speed is predicted to remain at its background levels and
geomagnetic conditions in the Australian region are expected to be
Quiet. Upon arrival of the CME the solar wind speed can increase to
moderate levels or higher and geomagnetic activity can reach Minor
Storm levels with possible isolated Major Storm periods.
High-frequency radio communication users are advised to use mostly
near predicted monthly frequencies. If communication difficulties are
experienced because of the anticipated geomagnetic storm, try a lower
frequency band.
