dc.description.abstract	GSC 4813-0981 = V921 Mon is a low-amplitude δ Scuti-type variable with an amplitude of 0.018m −0.027m in different bands and a period of 48.5 minutes. The fundamental parameters of the atmosphere and physical characteristics, determined from medium-resolution spectra, are: Teff=8700 K, logg=3.95 dex, [M/H]=0, M =1.7M⊙, R = 2.3R⊙. We performed a long-term analysis of the variations using a ten-year data set of CCD observations (2003?2013) acquired in BVR with the 1.5-m Russian-Turkish telescope (RTT150, TUBITAK National Observatory). A preliminary result is that the amplitude of the variability changes; it was decreasing during 2003?2008, but is now increasing.	ru_RU
