COMMENT: The greatest flare of the last 24 hours was an M5 peaking 
at 2249UT from region 1762(S28W85) which had early produced two 
C class flares. No other regions flared in the period. Coronagraph 
imagery is unavailable at time of writing to assess any possible 
CMEs from this flare, however the location of the region is unlikely 
to produce a geoeffective CME. More info will be given in tomorrows 
report is coronagraph imagery suggests otherwise. The solar wind 
speed is currently around 400 km/s. The IMF Bz component was 
southward by up to -13nT until around 15UT when it swung northward. 
Solar activity is expected to remain at low levels for the next 
3 days. A glancing blow from a CME is possible late on the 8th 
or early on the 9th of June (UT). Solar activity is expected 
to be low with a chance of moderate activity from region 1762 
before it finally rotates off the visible Sun. Activity is expected 
to be low for the following two days.

Observed Regional daily pc3 Indices 07 Jun : 
      Darwin               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: IPS Geomagnetic Warning 12 was issued on 7 June and 
is current for 7-9 Jun. Magnetic activity was Unsettled to Active 
with some isolated Minor Storm periods prior till around 14UT. 
After this time conditions were mostly Quiet. Mostly Quiet conditions 
are expected for most of the 8th of June UT. A glancing blow 
from a CME is expected late on the 8th or early on the 9th of 
June. This many cause Active conditions on arrival followed by 
Unsettled.
