Abstract: We report the observation of an extended γ-ray source named LHAASO J0534+3535 with a significance of more than 10 standard deviations for energy from TeVs to tens of TeVs. In addition to the γ-ray source detected by LHAASO, there is one old supernova remnant candidate, G172.8+1.5, and some GeV sources nearby. G172.8+1.5 is located in one of the largest star-forming regions in the outer Galaxy, characterized by HI gas that extends to velocities beyond those allowed by Galactic rotation, spanning an area of 4.4 degrees by 3.4 degrees at a distance of 1.8 kpc. LHAASO J0534+3535 is detected near the center of the supernova remnant G172.8+1.5, with an extension of approximately 0.5 degrees. Some results of the data analysis for J0534+3533 will be presented.
