Description
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°0farcm7
(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 300 GeV and a photon index Γ =
-3.10 ± 0.31stat ± 0.2syst.
