Observed Regional daily pc3 Indices 13 JUN : 
      Townsville           2   (Quiet)
      Learmonth            6   (Quiet)

      Hobart              37   (Quiet to unsettled)
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 13 Jun : A 
           Fredericksburg         7

15 Jun    16    Unsettled to active 
16 Jun    12    Unsettled 
COMMENT: Active and isolated minor storm periods are possible 
for the next two days as the result of glancing blows from recent 
CME activity and a possible increase in solar wind speed from 
a small coronal hole.
