Photoelectric UBV photometry of EK TrA during both types of outbursts (short eruption and supermaximum) is presented. The light curve of the short eruption is smooth without periodic features. During supermaximum, pronounced superhumps with an amplitude of 0.24 mag and a period of 0.0649 d were observed. The superhump period is confirmed by visual observations. A short comparison with other SU UMa stars is given.
