SUMMARY FOR 04 NOVEMBER AND FORECAST FOR 05 NOVEMBER - 07 NOVEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 04 Nov:  Very low

Flares: None

Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Nov:  71/6

1B. SOLAR FORECAST
             05 Nov             06 Nov             07 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 320 km/s over the 
last 24 hours. The north-south component of the interplanetary 
magnetic field ranged between ~ -1 and 4 nT. Possible CME was 
observed on the east limb at ~ 11 UT but is not expected to be 
Earth directed. Solar wind parameters are expected to become 
disturbed possibly late on 5 Nov or 6 Nov in response to a coronal 
hole 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.

05 Nov     5    Quiet 
06 Nov     8    Quiet to unsettled 
07 Nov     5    Quiet 

COMMENT: Field is expected to become disturbed possibly as early as
late today due to a recurrent coronal hole. An isolated active period 
possible on 6 Nov.
