Cubic Fit to the 2012 DA14 Observations

There was enough data to get a cubic fit to the 2012 DA14 observations. The results are shown in the image below. The positions are again given relative to the Earth-Moon barycenter.

The extrapolated close approach is Feb 15, 2013 19:54 UT.  There was little change in the minimum distance.

The Earth's gravitational attraction should change the results some.
