COMMENT: The ionospheric propagation support was strongly enhanced
for most of the day at most Australian stations during 20 Nov.
The preliminary observed T index was close to 150, far above
the predicted monthly value of 71. The propagation support is
expected to remain strongly enhanced in comming days, but eventually
weaken as the ionosphere begins to respond to the gradual decline
in solar UV flux. There is a declining chance of a SWF due to
an M-class solar flare during the next 48 hours.
