Abstract

We report on the advancements of a project which studies the Galactic bulge throught the kinematics of the stellar population in several low foreground extinction windows. In order to obtain the kinematics of as many stars as possible we have used the technique of proper motions in several fields with Hubble Space Telescope (HST) observations available. These proper motions have been complemented with radial velocities whenever possible. Our preliminary results consist of a sample of ∼ 140,000 proper motions with accuracies >1(mas\ yr(-1) ) distributed over 10 fields strategically placed at both ends of the Galactic bulge/bar.
