JPL orbit solution 16 for 'Oumuamua, with non-gravitational parameters

207 observations, solution dated 26 June 2018 (Farnocchia), with model exponents k=2.6, m=2, n=3 and R0=5 au (Micheli solution 7c). Horizons warns that ephemerides outside the observed arc are poorly constrained, which matters for any back-integration. NASA/JPL data are US government works.
