%X All available V-band optical data on H0323+022 from a good many of references ar e compiled.The long-term light curve in the V_band from 1982 to 2003 for BL Lac object H0323+022 is obtained, and the optical photometry of the sourse,which were observed with the 1 m telescope of Yunnan Astronomical Observatory and 1.56 m telescope of Shanghai Astronomical observatory,is presented.Observed results show significant rapid variation and exhibit short_time variability of 23 min in R band.It is found a strong correlation between the B-V colour index and the mag nitude in the B band. CCD photometry of H0323+022 showed that they are in good a greement with the results of Bai et al (1998).It is possible to estimate a b lack hole of emitting region R from the shortest time scale of H0323+022 object.
