[ips-sf] SWS Summary Forecast for 05 November - issued 2329UT/04-Nov-2018 [SEC=UNCLASSIFIED]

[rwc]

Solar activity was Very Low today (UT day 4 November). Solar activity
is expected to stay at Very Low levels for the next three UT days (5-7
November). Geomagnetic activity in the Australian region increased
from Quiet to Active levels today. Global geomagnetic activity may
stay high up to Unsettled to Active levels with a small possibility of
isolated minor storm periods on UT day 5 November and then show a slow
decline from Active to Unsettled levels through 6 November and return
to Quiet to Unsettled levels on 7 November. MUFs were mainly near the
monthly predicted levels today with minor to mild depressions observed
in some mid-latitude regions and minor to mild enhancements in
low-latitude regions. Minor to moderate MUF depressions and
degradations in HF conditions may be expected for the next 3 days due
to some possible enhancements in geomagnetic activity levels on 5 and
6 November and due to the continued very low levels of ionising
radiation.
