COMMENT: Solar activity was low over the last 24 hours, with 
the largest event being a C2 from region 2222 (S19W91). The solar 
wind speed has reduced slightly to around 700 km/s. The IMF Bz 
component varied between +/-6 nT. Solar wind speed is expected 
to continue declining over the next 3 days.

Observed Regional daily pc3 Indices 08 Dec : 
      Darwin              80   (Active)
      Townsville          13   (Quiet)
      Learmonth            0   (Quiet)

      Gingin              96   (Minor storm)
      Canberra           113   (Major 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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.

COMMENT: IPS Geomagnetic Warning 18 was issued on 7 December 
and is current for 7-9 Dec. Geomagnetic conditions were quiet 
to unsettled over the Australian region during the last 24 hours, 
with conditions reaching storm levels in the Antarctic. Unsettled 
periods are expected to continue over the Australian region on 
9-Dec, with activity declining during 10-11 Dec as the solar 
wind speed decreases.
