UV Tri was observed photometrically from 1999 to 2000. A period analysis of the data reveals two pulsation frequencies at 9.3299 and 10.8483 c d-1. From uvbyH β data we derive V = 11.085, b – y = 0.215, m 1 = 0.169, c 1 = 0.783, and β = 2.775 mag. With these color indices and some calibrations, we obtain Mv = 2.44 mag, M bol = 2.27 mag, Teff = 7500 K, log L/L ⊙ = 0.99 and a distance of ∼536 pc.
