We present a proper motion mini-survey of 35 fields in the vicinity of Baade window, (l, b) = (1{deg}, 4{deg}), sampling roughly a 5x2.5deg^2^ region of the Galactic bar. Our second epoch observations collected with the Advanced Camera for Surveys/High Resolution Channel instrument onboard the Hubble Space Telescope were combined with the archival Wide Field Planetary Camera 2/PC images. The resulting time baselines are in the range of 4 to 8yr. Precise proper motions of 15863 stars were determined in the reference frame defined by the mean motion of stars with magnitudes between I_F814W_=16.5 and 21.5 along the line of sight.
