Notes: Abstract We have established that the cataclysmic variable TU Crateris is an SU UMa star. Superhumps were observed after 3 days of the 1998 March-April supermaximum, repeating with a mean period of Ps = 0d.08535(5). Timings of superhump maxima revealed a period decrease of P = 7.2 × 10-5. Based on an empirical relationship, we estimated an orbital period of 0d.0810(25), just in the lower limit of the reported quiescence photometric period. Hα emission lines during quiescence vary with the orbital period with radial velocity half amplitude of 70 ± 19 km s-1, evidencing a hotspot located in front of the standard position.
