SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 01/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 01 NOVEMBER AND FORECAST FOR 02 NOVEMBER - 04 NOVEMBER
STATUS INDICATORS SOL:** YELLOW **   MAG:** YELLOW **     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 01 Nov:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Nov: 162/116


1B. SOLAR FORECAST
             02 Nov             03 Nov             04 Nov
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   170/124            175/129            180/133
COMMENT: Solar region 162 has departed the solar disk. Still 
maintaining watch on east limb around the solar equator for any 
signs of an active region, after yesterdays simultaneous flare 
in EIT with the X1 xray event. Solar proton flux levels are mildly 
enhanced 1 proton flux unit at the 10MeV energy level. A isolated 
equatorial coronal hole is now at the centre of the solar disk 
(visible in SOHO EIT 284 imagey). Solar region 177 in the north-east 
solar quadrant has shown rapid growth overnight.

      Hobart              28   (Quiet to unsettled)
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.

COMMENT: Degraded HF conditions expected 03-04 Nov at high latitudes. 
Polar regions may experience increased absorption due to mild elevation
in proton flux levels.
