BVR observations for 52 standard stars were performed using the 1-m reflecter with 2K CCD System of Chungbuk National University Observatory(CBNUO) in 2008. We obtained 1,322 CCD images to establish a correlation between our bvr system and the standard Johnson-Cousins BVR system. We derived the tentative equations of transformation between then as follows; V = v-0.0303(B-V)+0.0466 B-V = 1.3475(b-v)-0.0251 V-R = 1.0641(v-r)-0.0125 Using these equations the magnitudes in V, B-V, and V-R for 197 stars were obtained.
