Scientific paper

Using an ancient Chinese record about a great new star (supernova) in the 14th century B.C., we explain the gamma-ray flux from the gamma-ray source 2CG 353 + 16. We assume that the SN exploded in the molecular cloud Rho Oph in the 14th century B.C.; the cosmic rays were generated during the initial stage of the evolution of the remnant. The high-energy protons in the cosmic rays interact with the protons in the Rho Oph cloud and produce gamma-rays. The calculated gamma-ray flux is coincident with the observed one. The remnant of the SN is still embedded in the cloud and cannot be observed due to extinction.
