 Hi all -
 I checked that "SAT TRACK PHOTO" in the October Sky & Telescope
that folks have been talking about here recently.  What impressed
me is how odd it seemed that there would be 4 tracks, exactly
parallel and only a few arc seconds apart, that happened to pass
exactly through the location of Theta Orionis - the Trapezium, a
quadruple star.  And intersecting that at exactly a right angle
are two more precisely parallel tracks that also pass directly in
front of the Trapezium!  I submit, folks, that these "tracks" are
most likely a diffraction pattern of the Trapezium caused by some
structure in the optical system of the telescope.  The caption
states that the telescope in question is a refractor, so I don't
know what would be causing this diffraction.  If it were a
newtonian reflector, the diagonal mount would be the obvious
culprit.  Anyway, that's my guess as to which satellites these
are.
