      Hobart              21   (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 Sep : A

14 Sep     6    Quiet 
15 Sep     6    Quiet 
16 Sep     8    Quiet to Unsettled 
COMMENT: A period of mildly elevated solar wind speeds resulted 
in some unsettled levels of activity during 13 September. Mostly 
quiet conditions are expected over the next few days. A recurrent 
weak coronal hole may lead to unsettled conditions in 3 days 
time.
