We report the results of time-resolved CCD photometry obtained with the Mount Laguna Observatory 1-m reflector of the SU UMa star OT J011306.7+215250, which was discovered on 2008 Sep 22 UT by Drake et al. (ATel #1734) as part of the Catalina Real-time Transient Survey. A total of ~25 hours of V-band photometry over 5 nights (2008 Sep 25 - 29 UT) has enabled us to confirm its SU UMa nature, and to establish a revised superhump period of 0.09445(3) days (136.0 minutes), which is one of the longest superhump periods known.
