    Dave, can you provide the coordinates of your site?
    What is the estimated accuracy of the observation time? 
    How certain are you that it was directly overhead, i.e. ~90 deg elevation? I ask, because it is
    common to over-estimate elevation; for example, an object at 70 deg elevation may be perceived to be
    overhead. If you were laying on your back, then you could easily see directly overhead, but if you
    were standing, then you would have had to tilt your head far back, and also lean back quite a bit.
    Do you have any recollection of the star background? The identity of a near-by bright star, or
    constellation would be helpful information, if available.
