Abstract With this proposal we continue a succesful programme to measure proper motions in fields in the galactic bulge. We are able to reach accuracies of ca 10km/s in transverse motion at a distance of 8kpc, for thousands of stars per WFPC2 field. In combination with VLT spectroscopic radial velocities and metallicity indices, we will be able to construct a full dynamical and stellar-population model for our Bulge. Previous fields in this programme were on the minor axis; the fields proposed here (using first epoch observations from 1995-1998 from the archive) lie in the first quadrant, on the near side of the Galactic bar. We also wish to establish first-epoch observations in the 4th quadrant, where no suitable data exist so far. ------------------------------------------------------------------------------------ Observations Description ------------------------ Repeat observations of Galactic bulge fields, previously observed with WFPC2 in 1995-1998. Aim is to measure transverse motions to an accuracy of 10-20km/s at 8kpc, for bulge mani sequence stars. Specific ORIENT values are required (to within +/- 2D) in order to ensure clean overlap between the WFPC2 CCDs and those of ACS/WFC.
