Observed Regional daily pc3 Indices 12 OCT : 
      Townsville           0   (Quiet)
      Learmonth           NA
      Canberra             2   (Quiet)
      Hobart               2   (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 12 Oct : A 
           Fredericksburg         8
           Planetary              8                         

Observed AFr/Ap Indices 11 Oct :  A   K
           Fredericksburg         5
           Planetary              8   2223 3222     


2B. MAGNETIC FORECAST 
Date      Ap    Conditions
13 Oct    10    Quiet to Unsettled 
14 Oct    10    Quiet to Unsettled 
15 Oct     8    Quiet to Unsettled 
COMMENT: The north-south component of the interplanetary magnetic 
field has remained moderately southward. Unsettled to active 
periods may be experienced today at high latitudes due to sustained 
southward IMF.
