This target is often mentioned as V741 Per in the literature, e.g., also in the catalogs of Allen (1984) and Kenyon (1986), by mistake. Drummond (1980) reported the detection of a period of 4.0002 h in the light curves and suggested that the targets is an eclipsing binary with a short orbital period. Grauer & Bond (1981) did not detect similar period and suggested the orbital period to be longer than a half year. The 4-h period was not detected by Yamasaki et al. (1984) neither. Arkhipova & Noskova (1988) detected slow brightness variations which is supposed to be of an orbital origin (Arkhipova et al., 2008). Munari et al. (2012) also detected 6.4 and 1.18 d variability in the LCs. They suggested that the 2x6.4 d period might be the orbital period of this system (if the red giant is Roche lobe filling).
