Currently there are no sunspot groups on the solar visible disk. Very
low solar flare activity. A large recurrent coronal hole has taken
geoeffective position on the solar disk. As a result, today, (23
November) solar winds are expected to reach strong levels. If the
Interplanetary Magnetic Field (IMF) turns southward for a prolonged
period, geomagnetic activity may reach Major Storm levels,
particularly at higher latitudes. Thus there is chance that aurora may
be visible at the local night, today, from Tasmania and parts of
Victoria, Australia. HF radio communications fair to normal at low to
mid latitudes with isolated degraded conditions at high latitudes.
