ISSUED AT 06/2330Z FEBRUARY 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 06 FEBRUARY AND FORECAST FOR 07 FEBRUARY - 09 FEBRUARY
STATUS INDICATORS SOL:** YELLOW ** MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 06 Feb: Low
Flares Max Fadeout Freq. Sectors
M1.2 0349UT possible lower E. Asia/Aust.
Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Feb: 150/105
1B. SOLAR FORECAST
07 Feb 08 Feb 09 Feb
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 155/109 160/114 165/119
COMMENT: Solar region 278 in the north-east solar quadrant produced
the M1 event. The event had an unusual xray flare profile but
no mass ejection or radio sweep was observed. A mass ejection
was observed starting at around 06UT, assumed to be a behind
the limb event. Isolated M class activity expected. Solar wind
speed remains moderately elevated at 500km/sec due to coronal
hole effects. Bz fluctauting +/-5nT around neutral.
