1A. SOLAR SUMMARY
Activity 07 Jun:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Jun:  69/3

COMMENT: Solar activity was Very Low during the UT day, 7 June. 
There are currently no numbered sunspot regions on the visible 
disk. For the next 3 UT days, 8-10 June, solar activity is expected 
to remain at Very Low levels with a slight chance for C-class 
flares. No Earth-directed CMEs were observed during the UT day, 
7 June, in LASCO C2 imagery up to 07/2036 UT. During the last 
24 h, the solar wind speed decreased from 430 km/s to currently 
around 380 km/s. The IMF Bt reached a maximum of 11 nT at 07/0641 
UT,then began to decrease, currently around 4 nT. The Bz component 
of IMF was predominantly northward and ranged between -3 nT and 
8 nT. The outlook for 8-10 June is for the solar wind speed to 
remain at nominal values.

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: Geomagnetic conditions across the Australian region 
on UT day, 7 June, were mainly at Quiet levels, with a Quiet 
to Unsettled period at the start of the UT day. Geomagnetic activity 
is expected to be Quiet on the UT days, 8-10 June, as the solar 
wind has returned to nominal values.
