In this study, we investigate the present magnetic lattice of the UVSOR electron storage ring to explore the possibility to get a lower emittance with some minor changes in the configuration of magnets. For this purpose, we surveyed the periodic solutions as drawing a tune diagram to map the emittance and the dynamic aperture. Although, we could not find a solution which has a drastically small emittance, we have found a few solutions which has a small emittance around 10 nm, which is significantly smaller than the present value, 17nm. They may be useful for some special low emittance operation modes dedicated to developments on new light sources technologies and their applications.
