COMMENT: Equatorial latitudes (PNG, Niue, Nth QLD) have shown
ionospheric depressions, particularly during the daytime and
pre-dawn. This is presumed due to geomagnetic activity from the
coronal-hole induced solar-wind speed elevation. Mid-latitudes
appear to be still be holding better but are a little depressed.
Conditions should return to normal in a day as Vsw declines to
average. Spread F was not as prevalent as expected but did occur
significantly at mid to higher latitudes (e.g. Hobart)
