Geomagnetic field for Australian Region 06 Nov: Mostly unsettled to active
with storm periods observed at high latitudes.

Observed Regional daily pc3 Indices 06 NOV : 
      Townsville           6   (Quiet)
      Learmonth           12   (Quiet)
      Canberra           127   (Severe storm)
      Hobart             143   (Severe storm)
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 06 Nov : A 
           Fredericksburg        15
           Planetary             17                         

Observed AFr/Ap Indices 05 Nov :  A   K

           Planetary             19   3444 4333     


2B. MAGNETIC FORECAST 
Date      Ap    Conditions
07 Nov    20    Unsettled to active with possible minor storm 
                periods at high latitudes. 
08 Nov    15    Unsettled to active 
09 Nov    10    Quiet to Unsettled 
COMMENT: Solar wind parameters indicate the Earth is still under 
the influence of a high speed coronal hole solar wind stream, 
which has resulted in mostly unsettled to active levels with 
storm periods at high latitudes. The coronal hole solar wind 
stream is expected to decline slowly over the next 24 hours with 
mostly unsettled to active levels anticipated, and possible isolated 
storm levels at high latitudes.

COMMENT: HF conditions have been mostly near predicted monthly 
values to enhanced over the past 24 hours with slight depressions 
up to 15% at times due to elevated geomagnetic activity levels. 
Similar conditions are expected for 7 November.
