SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 13/2330Z OCTOBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 13 OCTOBER AND FORECAST FOR 14 OCTOBER - 16 OCTOBER
STATUS INDICATORS SOL:* YELLOW *   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 13 Oct:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 13 Oct: 179/132


1B. SOLAR FORECAST
             14 Oct             15 Oct             16 Oct
Activity     Low                Low                Low to moderate
Fadeouts     None expected      None expected      Possible
10.7cm/SSN   180/133            175/129            175/129
COMMENT: Solar activity was generally low. A C4 event with associated 
Type II/IV radio sweep was reported at about 1750UT. LASCO imagery 
is not available for analysis of any associated CME from the 
event, but possible shock arrival time would be late UT day Oct 
16 to early Oct 17. Proton flux was mildly elevated for a short 
time after 00UT but returned to previous levels.

Observed Regional daily pc3 Indices 13 OCT : 
      Townsville           0   (Quiet)
      Learmonth           NA
      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.

Estimated AFr/Ap Indices 13 Oct : A 
           Fredericksburg         6
           Planetary              9

2B. MAGNETIC FORECAST 
Date      Ap    Conditions
14 Oct     8    Quiet to Unsettled 
15 Oct     8    Quiet to Unsettled 
16 Oct    10    Quiet to Unsettled 
COMMENT: The north-south component of the interplanetary magnetic 
field has remained moderately southward. Unsettled to active 
periods may be experienced today at high latitudes due to sustained 
southward IMF.
