       Abstract: Loop I is one of  bright extended sources in the gamma-ray sky. The origin of Loop I is still an unresolved question. We analyze 9 years of the Fermi LAT pass 8 data to study the morphology and spectrum of Loop I and compare with observations in other wavelength. We also use a leptonic model to make a broadband fitting and compare the required spectrum with local measurement. The local source scenario with betatron acceleration may be excluded.
