Hot Jupiter candidates have consistently been prone to be false positives. Using data from the Transiting Exoplanet Survey Satellite (TESS) catalog, we assemble a sample of Hot Jupiters to conduct follow-up observations on. Follow-up observations allow us to rule out objects as false positives or confirm them as planets, helping to better understand TESS' false positive rate for Hot Jupiters. We use ground observatories for follow-up observations from two locations: Apache Point Observatory in Sunspot, NM, and Fan Mountain Observatory in Covesville, Virginia. These observations utilize bluer filters contrasting the redder bandpass of TESS' observations, in addition to an imaging resolution greater than that of TESS in order to collect data that we can analyze and use to either confirm or reject targets as Hot Jupiters. We present the preliminary results of the observations, photometric analysis, and modeling for two of the TESS objects of interest(TOIs) from our sample, TOI 1248 and TOI 1425, as false positives.
