We present the light curve and time series analysis of clasical novae and dwarf novae systems monitored/observed with the 1.5 m Russian-Turkish Joint telescope (RTT150) at the TUBITAK National Observatory in Antalya Turkey. As part of a large program V2275 Cyg (N 2001 No.2) RW Umi FO Per and PX And were observed for a total of about 25 nights The results on V2275 Cyg show that the system has a period of 0.463+/-0.014 or the 1-d alias 0.316+/-0.007 with wide eclipses (IAUC 8074). RW Umi shows possible periodicities at around several frequencies (approximate values in cyles per day 16.7 28.8 33.3 46.5 59 108.7) that could be interpreted as the binary period spin period of the white dwarf and/or orbital sidebands of the system.
