RS Car, V365 Car, V436 Car, AP Cru, RR Cha, BI Ori, CM Phe and V522 Sgr Patrick A. Woudt? and Brian Warner? Department of Astronomy, University of Cape Town, Private Bag, Rondebosch 7700, South Africa ABSTRACT Short time scale photometric properties of eight faint Cataclysmic Variable (CV) stars are presented. Nova Carinae 1895 (RS Car) has a photometric modulation at 1.977 h which could be either an orbital or a superhump period. Nova Carinae 1948 (V365 Car) shows flickering, but any orbital modulation has a period in excess of 6 h. The nova-like variable and X-ray source V436 Car has an orbital modulation at Porb = 4.207 h, no detectable period near 2.67 h (which had previously given it a possible intermediate polar classification), and Dwarf Nova Oscillations (DNOs) at ～40 s. Nova Crucis 1936 (AP Cru) has a double humped ellipsoidal modulation at Porb = 5.12 h and a stable modulation at 1837 s characteristic of an intermediate polar. Nova Chamaeleontis 1953 (RR Cha) is an ecliping system with Porb = 3.362 h, but at times shows negative superhumps at 3.271 h and positive superhumps at 3.466 h. In addition it has a stable period at 1950 s, characteristic of an intermediate polar. BI Ori is a dwarf nova which we observed at quiescence and outburst without detecting any orbital modulation. CM Phe is a nova-like variable for which we confirm Hoard, Wachter Kim-Quijano’s (2001) value of Porb = 6.454 h. We have identified the remnant of Nova Saggitarii 1931 (V522 Sgr) with a flickering source ～2.2 mag fainter than the previously proposed candidate (which we find to be non-variable). Key words: techniques: photometric – binaries: eclipsing – close – novae, cataclysmic variables 1 INTRODUCTION The first paper in this series (Woudt Warner 2001, Pape
