    Notes:
    
    (1) One unknown seen as follows:
    
        17h51m11.7s UT  RA 07h05m14.0s Dec +32d15'32" mag 8.2 steady
        17h51m31.0s        07h10m41.0s     +32d39'43" mag 8.2 steady
        17h51m38.2s        07h13m07.9s     +32d50'35" mag 8.2 steady
    
    A rough orbit determination gives an inclination around 18.1 degrees
    and height around 3400 kilometres - doesnt appear to be exciting and
    is probably an Ariane rocket casing in an eccentric orbit so pointless
    trying to locate it again as track arc above is inadequate.( I was
    obseving between gaps in a nearby tree so was unable to follow it).
    
    (2) The first 2 observations were obtained in a very bright twilight
    sky so accuracy may be a bit degraded. The same applies to satellites
    fainter than about magnitude 8.5 - anything fainter needs a little
    caution as satellites normally difficult to see.
    
    Cheers
