26 Feb   30      Normal            
MUFS:
   Equatorial PNG/Niue Region:
      Near predicted monthly values during local day,
      Enhanced by 20% during local night.

27 Feb   16      Normal            
MUFS:
   Equatorial PNG/Niue Region:
      Near predicted monthly values. Dusk enhancements noted
      at PNG (Vanimo, Pt Moresby) and Western Pacific (Niue).
   Northern Australian Region:
      Near predicted monthly values.
   Southern Australian and New Zealand Region:
      Near predicted monthly values. Spread F observed overnight
      in the Southern Ocean at Christchurch and MacQuarie Is.
      Strong sporadic E was also observed overnight at
      Hobart.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day. Strong
      Spread F observd inside the polar cap at Casey due to
      ionospheric convection resulting from prolonged
      ~20hr southward IMF Bz merging with the geomagnetic
      field.

At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
