N2 - The results of new photometric (VRI) observations of the young star V719 Per from the IC 348 cluster are presented. Up until 2014, this star demonstrated brightness variability typical for UX Ori stars, i.e., caused by strong fluctuations in circumstellar extinction. In 2014, the star dimmed by approximately 3 magnitudes in the I band and remained in that state until 2017. There is reason to believe that the eclipse was caused by a disturbance in the innermost regions of the star's protoplanetary disk. The dust raised above the disk caused the star's radiation to be blocked for approximately three years. The role of various processes in the generation of such disturbances is discussed.
