COMMENT: MUFs have picked up to near predicted monthly values,
due to ionising EUV and X-ray flux from active regions, particularly
AR1040, on the Sun. Sporadic E was noted through out the Australian
region. Near-equatorial sites had high MUF variability, probably
due to thermospheric winds and ionospheric electric fields, as
the geomagnetic activity was Quiet. Expect the solar active regions
to sustain ionisation and MUFs for several days.
