SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 06/2330Z FEBRUARY 2012 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 06 FEBRUARY AND FORECAST FOR 07 FEBRUARY - 09 FEBRUARY
STATUS INDICATORS SOL:** YELLOW **   MAG:GREEN     ION: GREEN

1A. SOLAR SUMMARY
Activity 06 Feb:  Moderate

  M1.0    2002UT  possible   lower  East Pacific/
                                    North American

Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Feb: 112/63

1B. SOLAR FORECAST
             07 Feb             08 Feb             09 Feb
Activity     Low to moderate    Low to moderate    Very Low
Fadeouts     Possible           Possible           None expected
10.7cm/SSN   110/60             110/60             100/48

COMMENT: Solar activity was moderate over the last 24 hours, 
with most activity from active region 1410 (N17W64), which showed 
some growth and produced an M1 flare at 06/2000. A CME observed 
early in the UT day is not expected to be geoeffective. Solar 
activity is expected to be low to moderate until AR1410 rotates 
off the disc. The solar wind speed has remained ~400km/s for 
the last 24 hours. The IMF Bz varied between +/-5nT, with a sustained 
southward period from 14-20UT. Some coronal hole effects are 
possible from late on 9-Feb.

      Davis               21   23432362

Observed Regional daily pc3 Indices 06 Feb : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Alice Springs        0   (Quiet)
      Gnangara             0   (Quiet)
      Canberra             0   (Quiet)
      Hobart               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 Space Environment Research Center, Japan.

COMMENT: Geomagnetic conditions have been mostly quiet, with 
an unsettled conditions from ~15-21UT corresponding to a sustained 
period of southward Bz. Quiet to unsettled conditions are expected 
for the next 3 days, with a possible increase in activity from 
late on 9-Feb, when mild coronal hole effects are expected.
