SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 13/2330Z JULY 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 13 JULY AND FORECAST FOR 14 JULY - 16 JULY
STATUS INDICATORS SOL:*YELLOW*  MAG:*YELLOW*   ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 13 Jul:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 13 Jul: 127/80


1B. SOLAR FORECAST
             14 Jul             15 Jul             16 Jul
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   130/84             130/84             130/84
COMMENT: Newly numbered region 409 has rotated around the east 
limb and is capable of producing further M-class flare activity. 
Solar wind parameters suggest the coronal hole wind stream presently 
effecting the Earth is declining.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 13 Jul: Quiet to Active 

Estimated Indices 13 Jul :  A   K

Observed Regional daily pc3 Indices 13 JUL : 
      Townsville           0   (Quiet)
      Learmonth           38   (Quiet to unsettled)
      Canberra           114   (Major storm)
      Hobart             116   (Major storm)
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.

Estimated AFr/Ap Indices 13 Jul : A 
           Fredericksburg        15
           Planetary             15                         

Observed AFr/Ap Indices 12 Jul :  A   K
           Fredericksburg        25
           Planetary             46   6764 3343     


2B. MAGNETIC FORECAST 
Date      Ap    Conditions
14 Jul    12    Unsettled 
15 Jul    20    Quiet to unsettled with possible active and isolated 
                minor storm periods. 
16 Jul    16    Unsettled to active 
COMMENT: Geomagnetic activity has been mostly unsettled to active 
over the past 24 hours as the coronal hole solar wind stream 
declines. Activity should remain mostly unsettled for 14 July, 
with activity expected to increase slightly for 15-16 July due 
to another coronal hole solar wind stream and possible transient 
from a recent disappearing solar filament.
