1A. SOLAR SUMMARY
Activity 02 Jan:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 02 Jan: 146/100

10.7cm/SSN   145/99             145/99             150/105

COMMENT: Solar activity has been low over the last 24 hours. 
Today's largest event was a C1.2 flare at 1948UT from region 
2256(S08W48). Solar wind speed showed a gradual decrease from 
nearly 450 km/s to around 370 km/s during the UT day today. The 
Bz component of IMF mostly stayed close to the normal value during 
the first half of the UT day and then varied between +/-5 nT 
staying south for relatively longer periods of time. Solar activity 
is expected to stay at low levels for the next three days with 
some possibility of isolated M-class event.

Observed Regional daily pc3 Indices 02 Jan : 
      Darwin               6   (Quiet)
      Townsville           0   (Quiet)

      Gingin               8   (Quiet)
      Canberra             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.

03 Jan    10    Quiet to Unsettled
04 Jan    10    Quiet to Unsettled
05 Jan    10    Quiet to Unsettled

COMMENT: Mostly quiet to unsettled conditions were observed today 
due to the declining effect of a high speed solar wind stream 
from a coronal hole. Due to exposure of the earth to high speed 
solar wind stream on 3 January and a possible effect of another 
coronal hole from 4 January, geomagnetic activity may rise to 
unsettled levels on 3, 4 and 5 January with the possibility of 
isolated active periods on all these days.
