Description We have re-analyzed old photometric UBV data obtained by Papoušek et al. at Skalnaté Pleso, Slovakia (1967 1980) and Brno, Czech Republic (1976 1979) observatories and analyzed new own CCD measurements (Brno, 2003 2005). In both set of photometric data the oscillations in the vicinity of the primary minimum were found. The detected periods are compatible with the previously published ones.
