The Galactic Bulge Valinhos Observatory Catalog (GBVOC) contains 11619 stars brighter than V~16 magnitudes, located in the direction of 12 low extinction windows of the Galactic bulge. The catalog provides the J2000.0 positions, proper motions at the mean epoch and their errors. These astrometric parameters were measured exclusively with CCD meridian observations realized at the Abrahao de Moraes Observatory Valinhos (Brazil) with a mean internal precision of 22mas for the positions and 4mas/yr for the proper motions. The catalog also contains the V magnitudes and mean epochs of observations. Moreover, an indicative effective temperature (better than 500K) based on the 2MASS photometry is given. The JHK 2MASS magnitudes and identifier are also provided. In the last column the capital letter T indicates that the star is present in the Tycho 2 catalog. (1 data file).
