The new photometric observational material of YY Her presented in this paper shows a very pronounced period of 587.54 days as well as its half value. Our results revealed the existence of secondary eclipses of the cool giant. The new ephemeris of primary minima is presented: JD(I,min) = (2450701.6 ± 1) d + (587.54 ± 0.5) d * E.
