This paper is devoted to observations of the poorly studied polar EU Lyn = SDSS J075240. 45+ 362823. 2. An analysis of observational data and a study of the literature shows that polar is possibly a faint close satellite (g 20m. 6) of the star (g 16m. 5) with the coordinates =07^\, 52^\, 40. 45, =+36^\, 28^\, 23. 2.
N. A. Katysheva (Mon,) studied this question.
