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.
