TU Tri: most likely SS Cyg star Dear Colleagues, We have mostly finished analyzing the January 4 data of TU Tri (4.5 hours, by Torii-san, RIKEN). The data do not apparently show superhumps, likely indicating that this object is an SS Cyg-type dwarf nova. An analysis of Jan. 5 observation will soon be undertaken. Regards, Taichi Kato
