[ips-sf] IPS Summary Forecast for 22 December - issued 0000UT/22-Dec-2014

[rwc]

Expect moderate to high solar activity. The CME occurring on 18
December hit the Earth's magnetic field, indicated by a weak impulse
observed by the BoM/IPS magnetometer network. There is a possibility
of aurora being observed in southern latitudes such as Tasmania at
local night time hours on 22 December. Geomagnetic activity has
increased to unsettled to active levels in the Australian region. The
solar wind has increased to moderate levels due to the arrival of the
CME. An X-class flare occurred at 0027UT on 20 December and is
expected to have a glancing blow at Earth over the next 24 hours.
Short-wave radio fadeouts likely. High-frequency radio communications
normal at this time.
