Abstract
We present an analysis of time-resolved, medium resolution optical spectroscopic observations of UX UMa in the blue (3920-5250 angstrom) and red (6100-7200 angstrom) wavelength ranges in April 1999 and March 2008, respectively. UX UMa has been in different states during those observations. Doppler tomography method was used to accretion disc structure investigation in both states. During the observations in 1999, UX UMa showed many of the defining properties of the SW Sex stars. However, all these features almost completely disappeared in 2008. We have also estimated the radial velocity semi-amplitude ICI.
