We report on photometric I-band observations of 147 bright (8<I<13) periodicvariables toward the Galactic bulge including 76 new discoveries. We used oneof the HATnet telescopes to obtain 151 exposures spanning 88 nights in 2005 ofan 8.4 x 8.4 deg^2 field of view (FOV) approximately centered on (l,b) = (1.73,-4.68). We observed the galactic bulge in 2005 as part of a microlensingfeasibility study (Nataf et al. 2009), and here we discuss the periodicvariables we found in our data. Among our discoveries we count 52 new eclipsingbinaries and 24 other periodic variables.
