Fermi LAT detection of a possible new extragalactic gamma-ray source in the vicinity of TXS 1530-131 (PMN J1532-1319)

The Large Area Telescope (LAT), on board the Fermi Gamma-ray Space Telescope, has observed a gamma-ray flare from a new gamma ray source. The preliminary best-fit location of the gamma-ray source (RA=233.16 deg, DEC= -13.35 deg, J2000) has a 95% containment radius of 0.32 deg (statistical errors only) for observations from May 23 to August 23, 2011. The flat spectrum radio source TXS 1530-131 (also known as PMN J1532-1319) (RA 15h32m45.3747s, Dec -13d19m10.086s, J2000, Kovalev et al.
