    Here's how I id this unid for him.
    
    I obtained following from him. 
    
    45.0914 N 075.3517 W
    
    I obtained the orbital elements from the analytical grpahics
    
    http://www.stk.com
    
    Must be a register user to access them.
    
    I then removed decayed objects, and added the classfd one's from mike mccants classfd.tle
    
    This is the resulting orbital elements file

    Details on the camera and refrence stars from him.
    
    The FOV is more like 17 x 13 arcmin (the MX9 is a reasonably big chip).  omicron Aurigae is
    at 5h45.9m RA and 49d50' dec.  SW UMa is at 8h 35.72m RA and 53d 28.7' dec.  These objects
    are not necessarily at the exact centre of the image, but are close enough given the FOV.
    
    I ran guide, enter his location, told it to use my file of orbital elements, set the date and time
    in local time  ( UTC-5 ) adjust the star feild to match his image. I ran a search for the time
    period given, nothing appeared. So I did a search a few minutes before and after. And the usa 136
    rocket appeared. I looked at it's track close to what his image shows, allowing for errors. The
    time was off, but that was to be expected from an object that is decaying like this one.
    
    Here's my image from guide showing the star feild. I obtained the usno A2 star catalog, so I could
    see fainter stars.

    Look like a positive match to me:)
