    Along the predicted trajectory two bright stars were expected, which are Altair 
    in Aquila and Deneb in Cygnus.
    
    Also in the video two bright stars can be spotted.
    
    The spacecraft was expected to be vertically below Altair at 22.57.08 UTC and 
    vertically above Deneb at 22.57.47 UTC,
    which is 39 seconds later.
    
    In the video the object is vertically aligned with the first star at the video 
    time 00:22 and with the second star at 01:01
    which is 39 seconds later as well.
    
    One thing that it is not consistent with the predicted trajectory is the 
    elevation of the object,
    which should have passed under Altair and not above. (this trajectory should 
    occur for an observer about 1.5 deg further North, always according to 
    predictons...)
    
    Here the two configurations:
