1A. SOLAR SUMMARY
Activity 23 Mar:  Very low

Flares: None

Observed 10.7 cm flux/Equivalent Sunspot Number for 23 Mar:  84/26

Fadeouts     None expected      None expected      None expected
10.7cm/SSN    84/26              85/27              85/27

COMMENT: New region, 1057 (N16E73), produced two sub-flares while 
region 1056 (N18W34) has decayed. Solar wind parameters were 
undisturbed. Solar wind parameters are likely to become disturbed 
early on 25th due to the effects of a coronal hole wind stream.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 23 Mar: Quiet with some
unsettled periods at high latitudes.

      Darwin               0   (Quiet)
      Townsville           0   (Quiet)

      Canberra             0   (Quiet)
      Hobart               0   (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 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 Space Environment Research Center, Japan.
