1A. SOLAR SUMMARY
Activity 04 Nov:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Nov:  79/19

COMMENT: Solar activity was low over the UT day, 04 October. 
Active Region (AR) 1121 (S20E69) produced B and C class X-ray 
flares during this period. Based on previous rotation as AR 1112 
and observed activity on the limb, expect this region to continue 
to produce B and C class flares with a moderate chance of an 
isolated M-class X-ray flare. AR 1120 (N38E08) continues to decay 
and is not expected to produce any significant flares. Solar 
wind speed varied between 340 and 280 km/s during the the last 
24 hours. The Bz component of the interplanetary magnetic field 
ranged between +2/-4nT. Expect this trend to continue today with 
solar wind speed in this range or slightly above.

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.
