SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z JANUARY 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 JANUARY AND FORECAST FOR 09 JANUARY - 11 JANUARY
STATUS INDICATORS SOL:** YELLOW **   MAG:GREEN     ION: GREEN

1A. SOLAR SUMMARY
Activity 08 Jan:  Moderate

Flares    Max     Fadeout    Freq.  Sectors
 M4/0F 07/2333UT  possible   lower  West Pacific

Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Jan: 174/128


1B. SOLAR FORECAST
             09 Jan             10 Jan             11 Jan
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   180/133            185/138            190/143
COMMENT: Solar region 251, located near the east limb, produced 
an M4.9 level flare at 07/2330. Several other C-class events 
occurred throughout the UT day, mainly from regions 244 and 242. 
A trans-equatorial north-polar coronal hole is in geoeffective 
longitude, and weak coronal hole wind stream effects may be 
experienced in the next few days.

Observed Regional daily pc3 Indices 08 JAN : 
      Townsville           0   (Quiet)
      Learmonth           NA
      Canberra             0   (Quiet)
      Hobart               7   (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 08 Jan : A 
           Fredericksburg         6
           Planetary              9

2B. MAGNETIC FORECAST 
Date      Ap    Conditions
09 Jan    10    Quiet to Unsettled 
10 Jan    15    Unsettled to Active 
11 Jan    12    Unsettled 
COMMENT: A trans-equatorial north-polar coronal hole is now in 
geoeffective longitude, and mild geomagnetic disturbance due 
to a weak coronal hole wind stream may be experienced over the 
next few days.
