    Morning all
    
    Basically a repost of the shadow entry observations of 
    geostationary satellites made on 5th Sept 2008 but this
    time includes RA and Dec of shadow entry point.
    
    Cheers
    Greg

     ==============================================================
     NOTES:
    
      1 :  SPACETRACK has 3 satellites here, only one seen
    
      2 :  SPACETRACK has 2 satellites here, only one seen
    
      3 :  SPACETRACK has 4 satellites here but unable to determine
                        which is which of the 4 seen.
                        
      4 :  From CLASSIFIED.TLE
    
      5 :  Bit difficult to decide which is which as SPACETRACK 
           predicted positions do not match very well. The satellites
           are: 
              98050A  25462
              00054A  26494
              00081A  26638
              01025A  26853
              
     6 :  Close grouping so not 100% sure which is which from 
          SPACETRACK predictions.         
                 
       
     7 : First two satellites done with MINTRON video camera but then
         switched over to using the DSI Pro 2 camera which gave much 
         better images and fainter penetration. The limiting star 
         background was about magnitude 12 to 13 andthe times given are
         when the satellite could last positively be seen at around
         magnitude 12 as it faded into shadow entry. Times should be
         accurate to within about 10 seconds,
