Abstract
UBV(RI)(c) observations of a G6/G8 IV star HD 17025 suggest a variatio n period of about 9 days. The light curve has a marginal amplitude of about 0.015 of a magnitude but is poorly defined and needs an independ ent confirmation. No prominent chromospheric emission is visible in a spectrum of this star. The other observed star, a K2 dwarf HD 38392, d id not show measurable light variations over a two weeks period of obs ervations.
