Resum

The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2hr in 2007 August-December. The observations resulted in the discovery of a γ-ray source centered at celestial coordinates R.A. = 2 h23m12s and decl. = 43°07 (MAGIC J0223+430), coinciding with the nearby radio galaxy 3C 66B. A possible association of the excess with the blazar 3C 66A is discussed. The energy spectrum of MAGIC J0223+430 follows a power law with a normalization of (1.7 0.3stat 0.6syst) × 10-11 TeV-1 cm-2 s-1 at 300GeV and a photon index Γ = -3.10 0.31stat 0.2syst. © 2009.
