Abstract
We discovered a new deeply eclipsing SU UMa-type dwarf nova, TY UMa, which experienced a superoutburst in 2000 January. Our monitoring revealed two di stinct outbursts, which suggest a superoutburst interval of similar to 800 d, or its half, and an outburst amplitude of 5.4 mag. From time-series phot ometry during the superoutburst, we determined a superhump and orbital peri od of 0.07588 d and 0.0739132 d, respectively.
