Ground-based light curve follow-up validation observations of TESS object of interest 3689.01

The Transiting Exoplanet Survey Satellite (TESS) mission, launched on April 18, 2018, was designed to collect data on objects in space that change in brightness and survey for transiting exoplanets (2). In this paper, we will be following up on TESS target of interest (TOI) 3689.01 using ground-based light curve observations. The data was collected from George Mason Observatory on September 15, 2023, using a red filter. We used the program AstroImageJ (AIJ) to reduce the raw data with dark subtraction and flat division before plate-solving. We also performed a NEB analysis, whose results were inconclusive. After looking at the light curve graph, we concluded that further observation must be done to confirm whether TOI 3689.01 is an exoplanet.
