93 observations of the seventh satellite of Saturn, Hyperion, with 473 observations of Titan—Saturn's sixth and the most massive satellite and the one nearest to Hyperion—are considered. The observations were made in 1967–1981 at several observatories. The values of (O–C) across and along the orbits are obtained. The normality of the distributions of (O–C) is studied.
