  We present new photometric observations of RV Tri.
  A complete light curve was obtained in the R and V filters.
  These light curves were processed by the Wilson-Devinney (WD) code and the
FOTEL to get solution of this eclipsing binary system. We discuss
characteristics of the system and compare our model with a previous
calculation. Our observations of primary minima and the comparison with those
predicted on the base of the GCVS catalogue indicates that there are
significant differences. We discuss these differences in the context of period
change.
