In this work we determine some parameters of the triple star HD 222326. The result is based on high-resolution spectra obtained at the coudÃ© echelle spectrograph of the 1.5Âm Russian–Turkish telescope RTT150 (AZT22). We redetermined the spectral class of the whole system and found high-amplitude short-time (relative to the known orbital period) variability of its radial velocity. This could be explained by the presence of the fourth component. Its nature is also discussed.
