摘要：
With the 6-m telescope we performed the magnetic field B (e) measurements for the chemically peculiar star HD 965. During 2000-2015 we obtained over 30 spectra with a Zeeman circular polarization analyzer. The longitudinal field reaches +600 G at the positive extremum and goes below -1300 G at the negative one. The magnetic monitoring of the star shows that the period of B (e) variability, i.e., the rotation period, exceeds 15 years. Thus, HD 965 belongs to the five slowest rotators among magnetic stars.
