SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z NOVEMBER 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 NOVEMBER AND FORECAST FOR 09 NOVEMBER - 11 NOVEMBER
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Nov: Very low
Flares: None
Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Nov: 71/6
1B. SOLAR FORECAST
09 Nov 10 Nov 11 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 visible disc is spotless. The solar wind speed rose
from about 270 to 450 km/s over the past 24 hours. The north-south
component of the interplanetary magnetic field ranged from about
-9 to 9 nT. STEREO imagery shows a CME erupting ~08/0400 UT,
probably from the far side.

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.
