Notes

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).
