A proper motion study of the globular cluster M 10
We present the first proper motion study of M 10 (NGC 6254). Absoluteproper motions of about 532 stars in the field of the globular cluster M10 were determined with respect to Hipparcos and ACT reference stars. Inaddition to photographic plates of Bonn and Shanghai also wide field CCDobservations as second epoch plates were used. The wide field CCDobservations show an accuracy comparable to that of the photographicplates. A good coincidence of the solutions based on reference starsfrom Hipparcos and from ACT was found. Our final proper motions allow asufficient separation of cluster and field stars. Two population IICepheids were confirmed to be members of M 10. The absolute propermotion of M 10 was determined and combined with its distance from theSun and its radial velocity. The space motion and metallicity of M 10indicates the characteristics of a halo object with an orbit reaching toa maximal z-distance of less than 3 kpc.
