Click here for a more recent pseudo-MPEC for this booster, based on further observations of this object.
TLEs are available for this and other objects on these pages. Also, you can get ephems for this object from the Minor Planet Center's DASO Page.
With additional data, we have a well-defined lunar miss distance of 11931 +/- 1 km, as well as a good post-flyby geocentric orbit.. The new observations don't link well with the old observations; it's safe to assume that the booster released some leftover propellant. I won't be surprised if further observations show that we have to reject even more of the early observations.

The object had some non-gravitational forces acting on it in the days after launch, probably remaining fuel boiling off. The final set of elements above is based on observations as the object went from the earth to the moon.
