Abstract (from CDS):

The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 hr in 2007 August-December. The observations resulted in the discovery of a γ-ray source centered at celestial coordinates R.A. = 2h23m12s and decl. = 43°0'.7 (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)x10–11 TeV–1 cm–2.s–1 at 300 GeV and a photon index Γ = -3.10±0.31stat ±0.2syst.
