Description

GJ3470b is a Uranus-mass exoplanet, orbiting around M dwarf (Bonfils et al. 2012). In this work, R-filter transit observations were conducted by using the 0.5-meter telescope at Thai National Observatory (TNO) and the 0.6-meter telescope at Cerro Tololo Inter-American Observatory (CTIO) in 2013-2015. From the light curves, the orbital elements of GJ3470b were obtained. In addition, the time of minima which obtained from observed data were used to compute O-C diagram. The result reveals that there is no major change in orbital period of GJ3470b.
