In this study, the analysis of the BVR multi-color photometric observation data of the V1817 Aql is presented. The photometric observation of the system were obtained during the 2024 observing season at the Çanakkale Onsekiz Mart University Astrophysics Research Center and Ulupınar Observatory using a MEADE LX200 model 30 cm Cassegrain-Schmidt telescope equipped with an SBIG STL-1001E CCD camera and BVR filters. The BVR light curves of the system were analyzed using the Wilson-Devinney code. The photometric mass ratio of V1817 Aql was determined to be 0.323±0.006. Accordingly, the mass and radius values of the components of the V1817 Aql binary system were derived to be M1=1.58±0.16 Mʘ, R1=1.47±0.12 Rʘ ve M2=0.46±0.10 Mʘ, R2=1.27±0.26 Rʘ and the evolutionary status of the components has been discussed.
