1A. SOLAR SUMMARY
Activity 29 Oct:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 29 Oct:  75/13

COMMENT: Solar activity was Very Low over the last 24 hours. 
There are currently 2 regions on the visible disk, region 2685 
(S08W33) and region 2686 (N13W10) and both remain relatively 
quiet and stable. No earthward directed CMEs were observed in 
the available LASCO C2 imagery. The solar wind speed gradually 
declined over the UT day from 374km/s to be ~320km/s at the time 
of this report. Bz ranged between +4 and -3nT. Very Low solar 
activity is expected for the next 3 days.

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.
