[AZ-Observing] NY40 daily motion

     Padraig Houlahan just pointed out that the motion of the asteroid
Saturday evening is about half that of the drift of stars in an undriven
telescope (half the sidereal drift rate).  And since it will be moving
nearly due west, we'll want to look for a star that is drifting through
the telescope field half-again faster than the stars themselves.
