    Observing under abominable conditions with many clouds, trying to do a planar 
    search for USA 161 (in vain, but given the conditions, I could have easily 
    missed any object, especially early in the window).
    
    USA 224 produces a naked eye flash and next was captured on one quite fogged 
    image, with only the starting point of the trail well-defined enough to measure it.
    
    40 seconds before this, in the same fog, a UNID was captured. I did not see it 
    visually, but encountered the faint trail on the image. Only one trail end was 
    measurable, and is reported here assuming an east-west movement.
    
    The UNID is *not* USA 161 as the trail direction is wrong (almost perpendicular 
    to what it should be).
    
    Trail length suggests a LEO, but cannot identify it with any object....
