    As to be expected tonight was cloudy....but with breaks.
    
    At 2238 I spotted Object B .it was to run below the roof line so from the 
    location of the scope could not be imaged , but I followed it through a 
    couple of gaps. It was very fast.
    This brief glimpse gave me a good impression of where to look for Object B 
    which was to follow 13 minutes later , nearly 40 degs higher in the sky..
    
    The cloud was not kind , but , I did manage to fire off a few frames when 
    "A" came zipping through.
    For the short time that I saw it it seemed to be at the predicted magnitude 
    of 1.5.
    
    My impression is that this bird is very much like USA 129 in design , with 
    perhaps a greater diameter conical "barrel" and panels along each side...a 
    cross perhaps between Arkon and Hubble.
    It is no more than about five metres in length.
    
    From the obs I would summise that this "is" an optical instrument.
    
    Four raw frames have been placed at
    
    http://satcom.website.orange.co.uk/     ( Recent Obs tag ) Range about 240 
    km
    
    On the left raw frames with dark frame subtracted...on the right the same 
    frames without DF.
    One of the solar panels is easy to see , the other slightly in shadow
    
    This is an exceptionally hard satellite to track due to its speed ( I 
    thought USA 193 was difficult , but this one takes the biscuit ! ) . . . but 
    considering the circumstances , the results , whilst  minimal , have given 
    us a number of pointers as to the design of this  bird.
