Photometric observations of the April 1989 superoutburst of SU UMa are presented. The periodic light variation, the superhumps, were discovered, proving that SU UMa is indeed a typical star of the SU UMa-type of dwarf novae and a good prototype of the class. The superhump period is equal to 113.4 min and is about 3 percernt longer than the orbit alone. It decreases during the superoutburst with the rate dP/P about 0.00006. Photometry obtained during the late stages of the superoutburst suggests the presence of so-called 'late superhumps'. The superhump profile has an evident, two-component structure which can be explained in the simplest way by the mass-transfer model.
