- Аннотация: SS Cyg is a well-known classical dwarf nova. For this class of cataclysmic variables, the short-term variability during the maximum and decline after it are typical: from the most rapid and coherent dwarf nova oscillations (10–30 sec periods, DNOs) to quasi-periodic oscillations (1–30 min, QPOs). Here we report the results of our CCD and broad-band photometric observations of SS Cyg carried out with the telescopes in Crimea during last years. The power spectrum analysis of CCD observations obtained during the 2006 outburst revealed oscillations with the two periods 10 sec and 76 sec. Moreover, the analysis of our photometric data taken during another outburst of SS Cyg show the existence of periodic oscillations on the stage of decline after maximum, too.
