SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 2330UT/15 FEBRUARY 2013 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 15 FEBRUARY AND FORECAST FOR 16 FEBRUARY - 18 FEBRUARY
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 15 Feb:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 15 Feb: 100/48


1B. SOLAR FORECAST
             16 Feb             17 Feb             18 Feb
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   100/48             105/54             105/54

COMMENT: The solar activity was Very Low during the UT day, 15 
February. Expect Very Low activity for the next three days. SOHO 
LASCO C2 imagery showed an CME first viewed at 1800UT on the 
northeast limb, not likely to be geoeffective. Solar wind speed 
declined from 390km/s to 330km/s over the last 24 hours. The 
Bz component of the IMF remained between +/- 2nT. Expect light 
solar wind over the next 24 hours.

      Mawson              20   22211256

Observed Regional daily pc3 Indices 15 Feb : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Alice Springs        0   (Quiet)
      Gingin               0   (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.
