Analysis of the pole orientation of 67P. Different RA/Dec measurements (blue dots) and respective error ellipses for individual epochs within an overall time period of one month indicate a precession. Nominal RA/Dec values (green dots) for a precession period of 10.7 days are within the error estimates. The black dot and the dashed black circle show the center of the precession cone and its estimated uncertainty.
