1B. SOLAR FORECAST
             04 Mar             05 Mar             06 Mar
Activity     Low                Low                Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   185/138            180/133            175/129
COMMENT: A CME observed at approximately 22UT on 2 March does 
not appear to be associated with any event on the frontside of 
the sun. It is therefore assumed to be a backside event and 
therefore not geoeffective.

Geomagnetic field for Australian Region 03 Mar: Quiet to Active 

Estimated Indices 03 Mar :  A   K           
   Australian Region      10   2333 2224

Observed Regional daily pc3 Indices 03 MAR : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Canberra            10   (Quiet)
      Hobart              13   (Quiet)
Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

Estimated AFr/Ap Indices 03 Mar : A 
           Fredericksburg         7
           Planetary              8                         

Observed AFr/Ap Indices 02 Mar :  A   K
           Fredericksburg         4
           Planetary              5   1111 1332     


2B. MAGNETIC FORECAST 
Date      Ap    Conditions
04 Mar    16    Quiet to unsettled with possible active periods. 
05 Mar    18    Unsettled with possible active periods. 
06 Mar    15    Quiet to unsettled with possible active periods. 
COMMENT: Active periods are possible for 4-6 March due to an 
anticipated high speed coronal hole solar wind stream.

06 Mar      Normal         Normal         Normal-Fair
COMMENT: Slightly degraded HF conditions are possible at times 
for 4-5 March as the result of anticipated mildly elevated geomagnetic 
activity levels.
