M. Iida (Nagano, Japan) reports on his discovery of an outburst of an obscure dwarf nova TU Tri. He gives an approximate unfiltered CCD magnitude of ~15.0 on Jan. 1.46. Follow-up observations are encourged. However, observers should note the coordinates and chart of TU Tri referred in GCVS are wrong. Downes & Shara (1993) provide a secure identification and J2000.0 coordinates of 01h 39m 15s.39 +31o 24' 19".8. Regards, Taichi Kato
