Scientific paper

We report observations of a ROSAT-discovered cataclysmic variable, RX J2353.0-3852. The optical spectrum shows strong, double-peaked Balmer emission, embedded in absorption troughs from Hβ onwards and similarly doubled He I and Fe II emission; He II λ4686 is not seen. Optical light curves obtained in 1993 November show a periodicity at 5246 sec with its first three harmonics, and another at 2282sec. These periodicities were not present in further observations made in 1994 September. A pointed observation in 1994 with ROSAT yielded a spectrum consistent with a dwarf nova with a low mass transfer rate.
