Description CCD photometry of QR And obtained in 2004 is reported. The lightcurves show changes in overall brightness on timescale of a week in range of ~0.30 mag, contrary to recently published results ~0.15 mag. With our data set we improved the orbital period and construct the first (O-C) diagrams.
