Ground-based Light Curve Follow-up Validation Observations of TOI-5352.01

The Transiting Exoplanet Survey Satellite (TESS) is a satellite that uses the transit method to detect exoplanets. This study aims to conduct a follow-up validation to confirm a transit through observations made with GMUs 0.8m telescope. After obtaining observation data and performing analysis with AstroImageJ, the follow-up data did not successfully confirm the presence of a transit consistent with the TESS observation. In particular, the predicted depth of 3.6ppt does not match with the observed depth of 5ppt, significant chunks of data are missing during the predicted transit time due to telescope error, and there is a large jump in the x and y values at the time of egress, suggesting that the observed transit is rather a product of the movement of the telescope. Therefore, it is necessary to conduct further observations in order to either confirm or reject the presence of an exoplanet.
