Remarks:
The variable stars were discovered within the framework of the Noosphere Education Support Fund project with the support of the Presidential Grants Fund and Sternberg Astronomical Institute of Moscow State University (SAI MSU). The search for variable stars was carried out using the ZTF project (Masci et al., 2019) data. Each star was discovered by schoolchildren, the authorship is indicated in the comments.

To perform photometry and to search for variable objects we used VaST software (Sokolovsky & Lebedev 2018).

The periodicity analysis was made with Period search service. Coordinates are drawn from GAIA EDR3. The data files contain Julian dates, magnitudes and uncertainties.
