Abstract: In this research, we conducted a search for new variable stars among recent Transiting Exoplanet Survey Satellite observations. We have chosen data from the 79th sector and a part of the 77th sector. As the main result, we discovered 191 variable stars with a sufficient signal-to-noise ratio that were not classified as variables before. We classified 43 of them and determined the variability period for 89 objects. In addition, we found an object with highly unusual changes in magnitude (TIC 149623590), for which we encourage further investigation. The objective of this project is to attract new citizen scientists to astronomy by conducting simple research under the supervision of more experienced mentors.
