I received news on a brand new discovery by the MAGIC collaboration today, and I wish to inform you about it. Here follows the communication from Mose' Mariotti on behalf of the MAGIC team:

The MAGIC Collaboration reports the discovery of VHE (E >100 GeV) emission from the new source MAGIC J0317+413. The source was in the field of view of the MAGIC telescopes between October 2009 and February 2010. The emission position is consistent with the head-tail radio galaxy IC310 (z=0.0189, RA: 03 16 43.0 Dec: +41 19 29, J2000) located in the outer region of the Perseus cluster of galaxies (Abell 426). A gamma-ray signal with a significance corresponding to >6 standard deviations was obtained from 20 hours taken in stereoscopic observation mode. An analysis of 38 hours of single telescope observations performed from 2008 to 2010 has confirmed the detection at ~6 sigma significance. Preliminary analysis indicates emission at the level of ~2.5% of the Crab Nebula flux above 300 GeV. The source was also recently detected in the Fermi/LAT data (A. Neronov, D. Semikoz, Ie.Vovk arXiv:1003.4615). The MAGIC Telescope system consists of two 17m diameter Imaging Atmospheric Cherenkov Telescopes observing gamma-rays at energies above 50 GeV. Both telescopes are operating together in the stereoscopic mode since the end of 2009.

MAGIC is a Cherenkov telescope for gamma-ray showers in the atmosphere. Recently, the main telescope has been doubled by the addition of a twin telescope, such that the system is now watching the night sky with a stereoscopic vision, which improves its detection capabilities and direction measurements. I think the discovery deserves some more careful discussion, but for now I just wished to make you aware of it!
