Six binary and candidate binary stars in the fields of V0873 Per and CV Boo were found using archive observations of the Mt. Maidanak Astronomical Observatory. (1) 2MASS J02465266+4125290 is a detached eclipsing binary with the period of P = 5ḍ 9436±0ḍ 0027. (2) TYC 2853-60-1 is a detached eclipsing binary with the period of P = 1ḍ 79 ± 0ḍ 01. (3) 2MASS J02475840+4116103 is an ellipsoidal binary system with the period of P = 0ḍ 30744±0ḍ 00005. (4) 2MASS J02464361+4120282 is a BY Dra-type binary star with the rotational period of P = 12ḍ 18 ± 0ḍ 06. (5) 2MASS J02465622+4117392 is an ellipsoidal binary system with the period of P = 4ḍ 022 ± 0ḍ 009. (6) 2MASS J15273711+3703070 is an ellipsoidal and/or RS CVn binary system with the period of P = 0ḍ 3307 ± 0ḍ 0002. Three of these stars exhibit chromospheric activity.
