Scientific paper

The results of spectral observations of the double system EY Ori at the second eclipse are presented. Some peculiar properties in the linear spectrum of the star have been discovered. The spectrum of the secondary component is not observed. The rotational velocity of the visible component is equal to 150±30 km/s. During the phases 0.52 - 0.58, during approximately 1d the radial velocities deviate from the radial velocity curve. According to the character of its spectrum, the system EY Ori is similar to typical Orion variables.
