We give a list of new variable stars in Perseus: area of 2°.3×2°.3, centered at α=02h00m δ=59°00′.
Our observations of the area in Perseus were performed at the observatory of Reshetnev Siberian State University of Science and Technology with a Hamilton telescope (D = 400 mm, F = 915 mm), equipped with an FLI ML9000 CCD chip (3056×3056 pixels, pixel size 12 μm). Exposures of all frames were 30 seconds. CCD-images were 2°.3 × 2°.3 square.
All unfiltered CCD-observations were obtained in the autumns of 2012, 2013, 2014 and 2017.
The magnitudes were referred to the unfiltered red band from the UCAC4 catalog (Zacharias et al., 2013) using VaST package (Sokolovsky & Lebedev, 2018). We also used VaST to search for new variable stars. To find periods, we applied WinEfk software provided by Dr. V.P. Goranskij.
This work was supported by Ministry of Education and Science of Russian Federation in the frame of state contract 3.6822.2017/7.8.
Acknowledgements: The authors wish to thank Dr. V.P. Goranskij for providing his efficient period-search software and Dr. Kirill Sokolovsky for providing VaST (a software package for detection of variable objects in a series of astronomical images).
