1A. SOLAR SUMMARY
Activity 06 Jul:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Jul:  76/14


1B. SOLAR FORECAST
             07 Jul             08 Jul             09 Jul
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    76/14              78/17              78/17

COMMENT: Solar activity was Very Low over the last 24 hours. 
Currently one sunspot group visible on the solar disc, active 
region 2665(S05E70). Expect Very Low to Low solar activity for 
the next three days. No Earthward bound CMEs observed from LASCO 
C2 imagery up to 06/2048UT. The solar wind speed ranged from 
310km/s to 375km/s over the last 24 hours and is currently 350km/s. 
The north-south component of the interplanetary magnetic field 
Bz ranged from +5/-6nT during this same period and Btotal varied 
between 2 to 8 nT. Expect the solar wind to remain in this range 
for the next 24 hours.

Observed Regional daily pc3 Indices 06 Jul : 
      Darwin               0   (Quiet)
      Townsville           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 International Center for Space Weather 
Science and Education, Japan.

COMMENT: Quiet conditions observed during the last 24 hours in 
the Australian region. Expect mostly Quiet conditions today, 
07 July. Late in the UT day, 08 July, expect geomagnetic activity 
to pick up due to equatorial positive polarity recurrent coronal 
hole becoming geoeffective.
