1A. SOLAR SUMMARY
Activity 08 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Jun:  74/11


1B. SOLAR FORECAST
             09 Jun             10 Jun             11 Jun

COMMENT: Solar activity was very low for the UT day, 8 June, 
with no notable flares. Very low levels of solar activity is 
expected for the next 3 UT days (9-11 June) with a chance of 
C-class flares. No Earth-directed CMEs were observed in the available 
LASCO imagery up to 08/1700 UT. The solar wind speed continued 
to trend near the nominal level of 310 km/s over the last 24 
hours. The IMF Bt was mostly steady near 3 nT during the UT day. 
The Bz component of the IMF varied between -4 nT and +2 nT, with 
no significant period of southward Bz conditions. The two day 
outlook (9-10 June) is for the solar winds to continue to trend 
near the nominal levels.

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.
