Murison continued looking into the question of extracting orbital information of a body (be it artificial satellite or binary star system) obtained from incomplete kinematics derived from observations (with errors) made from a moving platform. As the first part of the general problem, he completed a report, "Degradation of Error in the Longitudinal Coordinate of an Orbit from Astrometric Measurements", which considers just the determination of the target orbit radius and mean motion (and their errors) as well as the degradation with time of longitudinal errors.
Murison continued adding material to the two-body chapter of a possible book with Efroimsky, and probably E. Belbruno (Princeton), on Unconventional Celestial Mechanics.
Murison continued assisting in the development of AA's new web site.
Murison continued his DDA duties, helping the LOC with various tasks in preparation for the 2006 DDA meeting.
