Abstract
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 79.710.01 min is double humped; the superhump period is 81.7020.007 min. Towards the end of the outburst late superhumps with a period of 81.290.01 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.
