Abstract: We present the UBV(RI)C photometry of the dwarf nova Tri 2008 = OT J023839.1+355648 obtained during its superoutburst started on October 25, 2008. The object can be classified as a WZ Sge-type dwarf nova. The period of early superhumps 0.05307 days was detected in the first 7 days of the superoutburst. The period of ordinary superhumps 0.053663 days, detected in days 8-23 of the superoutburst, is the shortest one among WZ Sge-type objects. After one month, the dwarf nova returned to its pre-outburst state. A sudden increase of activity of the object during its quiescent stage was detected on January 11, 2009.
