The photometric CCD observations
for RR Lyr type star DM Cyg in Astronomical stations
near Odessa(Ukraine) and Kolonica(Slovakia) in
2008 and near Odessa in 2009 have been carried out.
The light curves in V system were obtained and the frequency
Fourier analyse was performed. From Fourier
spectra of the light curves 18 frequencies were identified.
The weak Blazhko effect was detected.
