SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 14/2330Z JANUARY 2004 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 14 JANUARY AND FORECAST FOR 15 JANUARY - 17 JANUARY
STATUS INDICATORS SOL:GREEN MAG:*YELLOW* ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 14 Jan: Low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 14 Jan: 121/73
1B. SOLAR FORECAST
15 Jan 16 Jan 17 Jan
Activity Low Low Low
Fadeouts None expected None expected None expected
10.7cm/SSN 125/78 130/84 135/89
COMMENT: Solar wind speeds have declined slowly during the past
24 hours, but still remain slightly elevated. Solar wind speeds
are expected to again increase by 16 January due to a coronal
hole rotating into a geoeffective position. There is the small
chance of isolated M-class flares from region 537.
