SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 07/2330Z NOVEMBER 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 07 NOVEMBER AND FORECAST FOR 08 NOVEMBER - 10 NOVEMBER
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Nov: Very low
Flares: None
Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Nov: 71/6
1B. SOLAR FORECAST
08 Nov 09 Nov 10 Nov
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 70/5 70/5 70/5
COMMENT: The solar wind speed remained below 280 km/s over the
last 24 hours. The north-south component of the interplanetary
magnetic field ranged between ~ -3 and 3 nT. Solar wind speed
is expected to increase today due to the effects of a coronal
hole high speed wind stream.

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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data.
NOTE: Indices may have been generated from data obtained in
cooperation with the following organisations: Geoscience Australia,
University of Newcastle Space Physics Group, Australian Government
Antarctic Division and Space Environment Research Center, Japan.
