The atmosphere of the HR8334 (v Cep, A2Ia ) star is studied by the atmosphere model. The eective temperature Teff of the star and the surface gravity g are determined by comparing the observational and theoretical estimates of equivalents widths W the Balmer lines Ha, H b, Hd and [c1],Q photometric indexes : Teff = 9200200K, logg = 1.4 0.2. Based on FeII lines the microturbulent velocity is determined: {t = 6km/sec. In the atmosphere of the star the iron abundances are calculated and compared
with the abundance in the Sun. The iron abundances are determined by the comparison of measured from observation and theoretically calculated values of equivalent width FeII lines. The iron abundance is close to the abundance in the Sun: loge (FeII) = 7.54.
