We present a multi-epoch Hubble Space Telescope (HST) study of stellar proper motions (PMs) for four fields along the Orphan stream. We determine absolute PMs of dozens of individual stars per target field using established techniques that utilizes distant background galaxies as stationary reference frame. Orphan stream stars are identified based on combined color-magnitude and PM information. In addition to the Orphan stream stars, we identified stars that likely belong to other kinematical component: the faint branch and the leading arm of Sagitarrius stream as well as an unknown component at a distance of \(\sim 12\) kpc.
