Solar:        Solar flare activity
Geomagnetic:  Geomagnetic activity observed for Australian Region.
Frequencies:  Australian Ionospheric F2 critical frequencies

24 Feb 
Solar:        very low
Geomagnetic:  Quiet 

Frequencies:  
   Equatorial PNG/Niue Region:
     Mostly near predicted monthly values,
     Depressed by 20% after local dawn.
  Northern Australian Region:
     Near predicted monthly values.
  Southern Australian and New Zealand Region:
     Near predicted monthly values.
  Antarctic Region (Casey/Scott Base/Davis/Mawson):
     Near predicted monthly values over the UT day.

25 Feb 
Solar:        very low
Geomagnetic:  Quiet 

Frequencies:  
   Equatorial PNG/Niue Region:
     Near predicted monthly values during local day,
     Enhanced by 30% during local night.
  Northern Australian Region:
     Depressed by 20% during local day,
     Enhanced by 15% during local night.
  Southern Australian and New Zealand Region:
     Near predicted monthly values.
  Antarctic Region (Casey/Scott Base/Davis/Mawson):
     Near predicted monthly values over the UT day.

26 Feb 
Solar:        very low
Geomagnetic:  Quiet to Unsettled 

Frequencies:  
   Equatorial PNG/Niue Region:
      Near predicted monthly values during local day,
      Enhanced by 20% during local night.
   Northern Australian Region:
      Near predicted monthly values.
   Southern Australian and New Zealand Region:
      Near predicted monthly values during local day,
      Enhanced by 15% during local night.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

27 Feb 
Solar:        very low
Geomagnetic:  Quiet 

Frequencies:  
   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.

28 Feb 
Solar:        very low
Geomagnetic:  Quiet 

Frequencies:  
   Equatorial PNG/Niue Region:
      Near predicted monthly values during local day,
      Enhanced by 30% during local night. Vanimo showed
      heavy absorption. Pt Moresby showed sporadic E at
      dawn.
   Northern Australian Region:
      Depressed by 20% during local day,
      Slightly above predicted monthly values during local night.
   Southern Australian and New Zealand Region:
      Near predicted monthly values during local day,
      Enhanced by 15% during local night.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day. Local
      varation with Casey, Scott Base and Macquarie Is
      showing slight enhancements, Davis showing slight
      depression.
