SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 17/2330Z NOVEMBER 2005 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 17 NOVEMBER AND FORECAST FOR 18 NOVEMBER - 20 NOVEMBER
STATUS INDICATORS SOL:** YELLOW **   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 17 Nov:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 17 Nov: 101/49


1B. SOLAR FORECAST
             18 Nov             19 Nov             20 Nov
Activity     Low to moderate    Low to moderate    Low to moderate
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   100/48             100/48             100/48
COMMENT: Active Region 822 remains the only significant feature 
on the visible solar disk. Flare activity over the UT day was 
limited to B-class, with a minor C-class event late in the UT 
day. The feint CME observed on 16 Nov in association with an 
erupting filament in the NW quadrant expanded into a partial-halo 
feature, which may have a weak earth-directed component. Further 
C- to M-class activity is possible from AR822.

of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.
