Significance skymap of the central region of the Perseus galaxy cluster from 45.7 h of MAGIC stereo observations taken between August 2010 and February 2011, above an energy threshold of 100 GeV. The NGC 1275 position is marked with a black cross, whereas the position of the radio galaxy IC 310 is shown by a green star. The PSF of about 0.12° is also displayed. The hot spot in the map at a significance level  > 6σ is consistent with a point-like emission coming from the NGC 1275 sky position.
