SUMMARY FOR 09 SEPTEMBER AND FORECAST FOR 10 SEPTEMBER - 12 SEPTEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 09 Sep:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 09 Sep:  91/36


1B. SOLAR FORECAST
             10 Sep             11 Sep             12 Sep
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    92/37              90/34              90/34

COMMENT: Solar activity was Very Low for the UT day, 09 September. 
Expect solar activity to be Very Low to Low for the next three 
days with a slight chance of an M-class flare which can be produced 
by AR2585 (now at N08W50). No Earthward directed CMEs were observed 
in available SOHO/LASCO imagery. The solar wind speed was varying 
in the range 460-400 km/s, slowly decreasing on average, currently 
the speed is around 420 km/s. The solar wind speed is expected 
to remain in the vicinity of its nominal levels during the next 
24 hours. The Bz component of the interplanetary magnetic field 
ranged between -4/+4 nT during the last 24 hours with Bt varying 
between 4 nT and 5 nT; currently Bt is 4 nT.

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.

Unsettled to Active period was also observed. For the next 3 
UT days, 10-12 September, geomagnetic activity is expected to 
be Quiet with possible isolated Unsettled periods.
