This paper reports the results from the multicolor photometric observations of 15 pre-main sequence stars collected in the period 2010 September – 2017 October. The stars from our study are located in the star-forming HII region IC 5070. These objects were previously detected as either emission line stars, flare stars, T Tauri variables or Herbig Ae/Be stars. Photometric observations, especially concerning the long-term behavior of the objects are missing in the literature. We present the first photometric monitoring for all stars from our study. The analysis of the obtained BVRI photometric data allows to draw a conclusion that all investigated objects are variable stars. In the case of LkHa 146 we identified previously unknown periodicity in its photometric variability.
