COMMENT: The equatorial ionosphere is still showing a strong
depression at night. Mid-latitudes appear mostly normal with
slight depletions across the day although some regions local
afternoon ionograms show enhancement. Many stations across the
east coast and southern Australia show strong morning sporadic
E at the time of this report. High latitudes are moderately disturbed
by enhanced polar cap convective flows due to geomagnetic merging
with the solar magnetic field (IMF).
