SUMMARY FOR 10 SEPTEMBER AND FORECAST FOR 11 SEPTEMBER - 13 SEPTEMBER
STATUS INDICATORS SOL:GREEN   MAG:** YELLOW **     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 10 Sep:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 10 Sep:  95/41

1B. SOLAR FORECAST
             11 Sep             12 Sep             13 Sep
Activity     Very low to low    Very low to low    Very low to low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    95/41              95/41              95/41

COMMENT: Two new bipolar regions at S13 W26 and S12 E10. There 
were two CMEs, observed in LASCO and STEREO images, associated 
with filament lift-offs from the eastern limb and the south-east 
quadrant. Neither CME is likely to be geo-effective. ACE data 
show the solar wind undisturbed until about 0830 UT. Wind speed 
steadily rose but remains under 400 km/s while the north-south 
IMF component range was +6 to -7 nT. A recurrent coronal hole 
is expected to influence the solar wind beginning 12 Sep.

Observed Regional daily pc3 Indices 10 Sep :

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.
