     This has me puzzled. The only bright satellites with this kind of inclination
     are the  two FIA satellites - neither of which were visible if 2 prediction 
    programs
     correct.
    The Israeli satellites dont have as high an inclination so what is this.
     Definately not  a bird or aeroplane.

     NOTES:
     ---------
     (1) Rather cloudy conditions with very heavy dew. Eventually stopped
        by rain.
    
     (2) Testing replacement lens for the Nikon. This lens is a TAMRON
        4 element lens made between 1976 and 1979. Focal length 135mm
        at f/2.8. Image quality at edges quite a lot superior to the
        Nikon (which cost a great deal more ), vignetting is less
        severe and almost no field curvature and so far no sign of internal
        reflections.
    
     (3) Bright unknown - no obvious match in my current element database
    
     (4) I did not bother to measure all the geosats seen in the wide field-
        only did classified objects - no satellites unidentified.
    
     (5) Looks like PAN has come to rest next to PAKSAT 1 - as usual not sure
        which satellite is which but took PAN to be the slightly fainter
        satellite to the east of PAKSAT 1.
    
     Cheers
