1A. SOLAR SUMMARY
Activity 11 Jan:  Very low

Flares: B class flares

Observed 10.7 cm flux/Equivalent Sunspot Number for 11 Jan: 108/58


1B. SOLAR FORECAST
             12 Jan             13 Jan             14 Jan
Activity     Very low to low    Very low to low    Low

10.7cm/SSN   108/58             105/54             100/48

COMMENT: Solar flare activity was very low during 11 Jan UT and 
is expected to remain very low to low during the next 2 days. 
A few C class flares are possible. GONG H alpha images show a 
large filament has rotated around the north east limb into view. 
There are no Earthward directed CMEs. The solar wind speed increased 
from about 400 km/s to about 650 km/s during 11 Jan. The solar 
wind speed is presently about 580 km/s and fluctuating. The magnitude 
of the IMF increased from about 3 nT to about 10 nT. The Bz component 
has been in the range -7 nT to +7 nT.

      Canberra            11   (Quiet)
      Melbourne           34   (Quiet to unsettled)

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: IPS Geomagnetic Warning 3 was issued on 10 January and 
is current for 12-13 Jan. Geomagnetic activity was quiet to unsettled 
throughout the Australian region during 11 Jan UT. The planetary 
Kp index reached 4 during 18-21 UT due to the arrival of fast 
wind exceeding 600 km/s. Conditions are expected to be unsettled 
to active during 12 Jan, returning to quiet by 14 Jan.

COMMENT: Conditions for HF radio propagation were mildly depressed 
in the Northern Hemisphere, and near predicted monthly values 
to enhanced in the Southern Hemisphere during 11 Jan UT. Support 
for HF radio propagation is expected to depress during 12-13 
Jan due to increased geomagnetic activity.

      No data available during local night.
   Northern Australian Region:
      Enhanced by 15% during local day.
      Enhanced by 25% during local night.
      Depressed by 30% after local dawn.
   Southern Australian Region:
      Mostly near predicted monthly values.
      Depressed by 25% after local dawn.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

12 Jan    50    Near predicted monthly values
13 Jan    55    Near predicted monthly values
14 Jan    60    Near predicted monthly values

COMMENT: Conditions for HF radio propagation in the Australian 
region were near predicted monthly values to enhanced during 
11 Jan UT. The enhancements were strongest at low latitude stations. 
Depressions are possible during 12-13 Jan due to increased geomagnetic 
activity.
