We report unfiltered CCD photometry of the eclipsing dwarf nova SDSSJ093249.57+472523.0 obtained during its first confirmed outburst in 2011 March.The outburst amplitude was at least 3.0 magnitudes above mean quiescence and itlasted at least 11 days, although we missed the beginning of the outburst.Superhumps having peak-to-peak amplitude up to 0.3 magnitudes were presentduring the outburst, thereby establishing it to be a member of the SU UMafamily. The mean superhump period was Psh = 0.06814(11) d. Analysis of ourmeasurements of eclipse times of minimum, supplemented with data from otherresearchers, allowed us to measure the orbital period as Porb = 0.06630354(5)d. The superhump period excess was epsilon = 0.028(1) which is consistent withof SU UMa systems of similar Porb. The FWHM eclipse duration varied between 6and 13 mins and the eclipse depth was up to 1.6 magnitudes.
