High resolution spectroscopic observations of BX And using the BOES (Bohyunsan Optical Echelle Spectrograph) of Bohyunsan Optical Astronomical Observatory (BOAO) were performed during 26-27, Feb. 2003. From the observations, we obtained 38 line spectra of BX And which cover all phases except the phase interval between $0.^{\rm p}1$ and $0.^{\rm p}3$. Both methods of the CCF (Cross-Correlation Function) and BF (Broadening Function) were used to get the radial velocities of primary and secondary components. Both velocities of the primary and secondary stars were calculated with the BF method while only primary velocities were determined with the CCF. Using new radial velocity curves, the maximum radial velocities of the primary and secondary stars were obtained as $K_1 = 96.1$km/s and $K_2 = 196.6$km/s, respectively. New absolute dimension of BX And was deduced with the combination of our spectroscopic solution with the photometric one of Bell \etal \ (1990). KCI Citation Count: 0
