SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 05/2330Z JANUARY 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 05 JANUARY AND FORECAST FOR 06 JANUARY - 08 JANUARY
STATUS INDICATORS SOL:** YELLOW **   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 05 Jan:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 05 Jan: 148/102


1B. SOLAR FORECAST
             06 Jan             07 Jan             08 Jan
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   150/105            150/105            155/109
COMMENT: Solar wind speed has declined to 400km/sec. The narrow 
north-polar extension trans-equatorial coronal hole visible in 
SOHO EIT284 imagery is now near the central meridian of the Sun. 
The high speed wind stream from this hole is expected 09-10 Jan. 
However, recurent patterns imply weak effects. Growth of on disk 
regions of interest has slowed. An increasing trend of solar 
activity is possible over coming days, due to possibilty of 
returning regions.
