dc.description.abstractThe variability of the star was found by C. Hoffmeister in 1936. The star thoroughly was investigated by V. P. Tsessevich, which determined the primary ele- ments of period: Max. hel. J.D. = 2436047.522 + 0.6130535 E, and discovered the sophisticated shape of light variation curves, known as Bllazhko effect (40.64 day) (Tsessevich, 1961, 1966). He mentioned, that the curve of maximum height shows considerable dispersion, and it seems, that the most part of time we ob- serve the weakened maxima and only in some time intervals (short-term) we observe the maxima in the considerable heights. It indicates in modulation of a light curves by additional frequencies, and the star represents the scienti c interest for observations. Visual observations in 20 century were carried out by Hoffmeister and Tsessevich. Now V365 Her is known as RR Lyr-star type (RRab) with amplitude 12:m7 14:m0 (P), has period 0:d613138, Kholopov et al. (1985).uk_UA
