I found my notes back and discovered that the direction the satellite went
is right.  I also wrote down the end of the time exposure so position 2 must
have been around 20h16m25s UTC.  


Mike McCants suggested the following elset:


1 99991U          93 85.83289575  .00000000  00000-0  00000+0 0    01
2 99991  99.1300 149.5698 0005000 163.1793 196.8207 14.20000000    08


Maybe the satellite was in a somewhat lower orbit making a mean motion which
is perhaps closer to 14.4.  Inclination should therefore somewhere around
98.6 degrees, but this is only a guess.  The three flashes visible on the
picture did have a magnitude of about 1 to 1.5.



Hope this will help the identification.
