The observation results of the explosion of the extragalactic Supernova remnant SN2006 gy (z=0.019) are presented. NGC 1275 has been regularly observed by SHALON since 1996. NGC 1275 is being intensively studied and the γ-ray flux is found to be . A flux increase was detected from the region NGC 1275 in autumn 2006. The detailed analysis of γ-shower direction resulted in the detection of a metagalactic object. This object was identified with the supernova SN 2006gy that is about 10′ away from NGC 1275. The integral γ-ray flux for SN 2006gy is found to be at energies of >0.8 TeV. The integral average γ-ray fluxes of Mkn 421 and Mkn 501 were estimated as and respectively. An increase of the flux over the average value was detected in the 1997 and 2004 observations of Mkn 421 by SHALON and estimated to be and , respectively. A significant increase of Mkn 501 flux was detected in 1997 with VHE ground telescopes worldwide.
