very enhanced nighttime ionisation for reasons not readily apparent.
Extensive spread-F at night at near-equatorial latitudes. MUFs
are expected to remain mostly normal across Aust/NZ region for
the next three days. Low possibility of slight disturbance in
1-2 days if an east limb CME shock front glances the geomagnetic
field.
