我们介绍了斯隆数字巡天激变变星SDSS J013701.06 - 091234.9在静止期和2003年12月超级爆发期间的高速测光。在79.71 ± 0.01 min处的轨道调制为双峰型，超峰周期为81.702 ± 0.007 min，在爆发末期观测到周期为81.29 ± 0.01 min的晚期超峰。我们认为，这是一个非常低的传质速率的系统，它可能有一个长的爆发间隔。
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.
