SUMMARY FOR 27 NOVEMBER AND FORECAST FOR 28 NOVEMBER - 30 NOVEMBER
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN

1A. SOLAR SUMMARY
Activity 27 Nov:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 27 Nov:  83/24


1B. SOLAR FORECAST
             28 Nov             29 Nov             30 Nov
Activity     Low                Low                Low

10.7cm/SSN    84/26              83/24              83/24

COMMENT: Solar activity was Very Low for the UT day, 27 November. 
Expect solar activity to be Low for the next three days with 
a slight chance of an M-class flare. No Earthward directed CMEs 
observed in the available SOHO imagery. Due to the continued 
coronal hole effect, solar wind stream is still enhanced, but 
decreased throughout the UT day from 660 km/s to around 570 km/s. 
Bt remained around 5nT. The Bz component of the IMF ranged between 
-/+ 5nT over the UT day. Solar wind stream is expected to continue 
to weaken over the next three days.

Observed Regional daily pc3 Indices 27 Nov : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)

      Melbourne           NA

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 International Center for Space Weather 
Science and Education, Japan.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY


Date   T index
27 Nov    16

Observed Australian Regional MUFs
   Cocos Island Region:
      No data available. 
   Niue Island Region:
      Depressed by 15% during local day.
      Near predicted monthly values during local night.
   Northern Australian Region:
      Mostly near predicted monthly values.
   Southern Australian Region:
      Near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Depressed by 15% over the UT day.

Monthly T index:

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
28 Nov    20    Near predicted monthly values
29 Nov    20    Near predicted monthly values
30 Nov    20    Near predicted monthly values

COMMENT: Improved ionospheric support observed today. MUFs were 
mostly near predicted monthly values in all regions. Sporadic-E 
events again observed throughout the region and strong blanketing 
Es that obscured the F-region. Expect continued improvement in 
ionospheric support for the next few days with possible continuing 
Sporadic-E events for Equatorial and Aus/NZ regions.
