We present high‐speed photometry of the Sloan Digital Sky Survey cataclysmic variable SDSS J013701.06 − 091234.9 in quiescence and during its 2003 December superoutburst. The orbital modulation at 79.71 ± 0.01 min is double‐humped; the superhump period is 81.702 ± 0.007 min . Towards the end of the outburst late superhumps with a period of 81.29 ± 0.01 min were observed. We argue that this is a system of very low mass transfer rate, and that it probably has a long outburst interval.
