  We present the first proper motion study of M10 (NGC6254). Absolute proper
motions of about 532 stars in the field of the globular cluster M10 were
determined with respect to Hipparcos and ACT reference stars. In addition to
photographic plates of Bonn and Shanghai also wide field CCD observations as
second epoch plates were used. The wide field CCD observations show an accuracy
comparable to that of the photographic plates. A good coincidence of the
solutions based on reference stars from Hipparcos and from ACT was found. Our
final proper motions allow a sufficient separation of cluster and field stars.
Two population II Cepheids were confirmed to be members of M10. The absolute
proper motion of M10 was determined and combined with its distance from the Sun
and its radial velocity. The space motion and metallicity of M10 indicates the
characteristics of a halo object with an orbit reaching to a maximal z-distance
of less than 3kpc.
