COMMENT: HF MUF conditions are expected to remain mostly normal
to slightly enhanced across Aust/NZ region for the next three
days. Nighttime MUF enhancements are noted in particular, possibly
due to prevalance of night spread-F in near equatorial regions.
Possibility of increased MUF enhancements and a slightly disturbed
ionosphere around the 13th due to the passage of a solar IMF
sector boundary, which may enhance the geomagnetic field disturbance
to Unsettled and in turn enhance and disturb the ionosphere.
