1A. SOLAR SUMMARY
Activity 04 Jan:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Jan:  86/29

COMMENT: Solar activity was very low on UT day 04 January. Newly 
numbered AR2924 (S32E52, Cso/beta) has grown since yesterday 
and there appears to be another region developing near N23E65. 
Solar activity is expected to be very low with a slight chance 
of C-class flares on 05 to 07 January. There were no Earth directed 
CMEs observed in available images. On 04 January, the solar wind 
speed range was 383 to 519 km/s. The peak total IMF was 7 nT 
and the north-south IMF (Bz) range was +3/-6 nT. Near background 
solar wind conditions are expected on 05 to 06 January. On 07 
January, a coronal hole wind stream may begin to elevate solar 
wind conditions.

      Townsville           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: On UT day 04 January, geomagnetic conditions in the 
Australian region were quiet. Quiet to major storm conditions 
were observed in the Antarctic region. Mostly quiet conditions 
are expected on 05 to 06 January. Activity may increase to unsettled 
to active levels on 07 January with the expected arrival of a 
coronal hole wind stream.

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
05 Jan    30    Near predicted monthly values with some depressions 
                to 20%
06 Jan    25    Near predicted monthly values with some depressions 
                to 20%
07 Jan    25    Near predicted monthly values with some depressions 
                to 20%

COMMENT: MUFs in the Australian region on UT day 04 January were 
near predicted monthly values with some depressions to 20%. Depressions 
20-50% were observed at Darwin 19-21 UT. Sporadic E was occasionally 
observed at Canberra, Hobart, Norfolk Is. and Perth, mostly during 
daytime. MUFs are expected to be near predicted monthly values 
with some depressions to 20% as ionising solar flux levels decline.
