FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 03 DECEMBER AND FORECAST FOR 04 DECEMBER - 06 DECEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 03 Dec:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 03 Dec:  95/41


1B. SOLAR FORECAST
             04 Dec             05 Dec             06 Dec
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              90/34              90/34

COMMENT: Solar flare activity was Low on 03 Dec. Active Region 
2458 (N09W79) produced a single C1 flare at 0628UT. The 3-day 
outlook is for Very Low solar activity with weak C class flares. 
No Earth-directed CMEs were observed in available LASCO imagery. 
Solar wind speed was steady at around 400 km/s. The Bz component 
of the interplanetary magnetic field ranged between +/-5nT. Solar 
wind speed is likely to reduce further on 04-05 Dec, before picking 
up 06 Dec due to coronal hole effects.

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 were Quiet throughout the Australian 
region during 03 Dec UT and they are expected to remain Quiet 
for the next two days. Conditions may become Unsettled to Active 
during 06 Dec due to the arrival of faster wind emanating from 
coronal hole.

05 Dec    50    Near predicted monthly values
06 Dec    40    Depressed 15%/near predicted monthly values

COMMENT: Conditions for HF radio wave propagation were mildly 
depressed throughout the Australian region during 03 Dec. Increased 
geomagnetic activity may lead to depressed HF propagation conditions 
during day three.
