To get a better picture of what 2012 DA14 is doing in 3D I used the previous set of observations and the corresponding fit to make an anaglyph. The horizontal axis is the RA in degrees and the vertical axis is the Decl in degrees so that both scales have the same unit of measurement. The separation of our "eyes" is the diameter of the Earth and our "vista point" is the Earth-Moon barycenter. The time span ranges from Feb 6.388 to Feb 11.496 and points further away occur earlier in time.
