In this project, 33 new transits of 4 close-in exoplanets: HAT-P-12b, Qatar-1b, HAT-P-37b, and WASP-77A b, are conducted, in order to update their linear ephemerides, physical properties, and to search for their transit timing variations (TTVs). The observations of HAT-P-12b, Qatar-1b, and HAT-P-37b were taken during 2011-2020 by 60-inch telescope at Palomar Observatory, the 0.5-m telescope at the Crimean Astrophysical Observatory, and the 2-m Himalayan Chandra Telescope at the Indian Astronomical Observatory. For WASP-77A b, the observations were acquired during 2018-2021 from 2.4-m and 1-m telescopes at the Thai National Observatory, and the 0.7-m Thai Robotic telescopes in China and Australia. In addition to presenting these new transit observations, the main conclusions about these planetary systems will be given.
