dc.descriptionNew CCD observations of the RRab star UX Tri after JD = 2452234 show a change of the main pulsation period. The period is now P = 0.4669046 +/- 0.0000006 [d]. The change is delta_P = - 1.72 x 10-5 [d] if compared with the value we previously published in IBVS 5210. A strong Blazhko effect with unchanged Blazhko period P_B = 43.7 +/- 0.1 [d] is confirmed by this paper. Light curve particularities around Blazhko phase phi_B = 0.0 are discussed in detail. In one observation (JD 2453617) related to Blazhko phase phi_B = 0.12 an exceptionally pronounced "bump" of delta_m > -0.1 magnitude was observed at pulsation phase phi = 0.71.
