A new flaring high-energy γ-ray source.

Abstract (from CDS):

We report the detection of a new γ-ray source in the Fermi-LAT sky using a source detection tool based on the minimal spanning tree algorithm. The source, not reported in previous LAT catalogues but very recently observed in the X-rays and optical bands, is characterized by an increasing γ-ray activity in 2012 June-September that reached a weekly peak flux of (3.3±0.6)x10–7 photons/cm2/s. A search for a possible counterpart provides indication that it can be associated with the radio source NVSS J141828+354250, whose optical SDSS colours are typical of a blazar.
