Abstract: NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered thousands of exoplanet candidates that require ground-based follow-up to confirm their planetary nature and eliminate false positives. One such candidate, TOI-7325.01, is predicted to exhibit a transit depth of approximately 5 ppt with a short duration. We conducted ground-based observations of TOI-7325.01 using the George Mason University 0.8 m telescope and processed the data with AstroImageJ (AIJ). A flux light curve was generated from plate-solved images, revealing a dip in stellar brightness near the predicted transit window. While technical limitations prevented completion of a Nearby Eclipsing Binary (NEB) analysis, leaving the possibility of contamination unresolved, our results provide preliminary support for the planetary interpretation of TOI-7325.01. These findings emphasize the continued need for ground-based monitoring to validate this candidate and refine its characterization.
