Fermi LAT Detection of a New Gamma-ray Source in the Vicinity of PMN J1038-5311

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 = 159.604 deg, Decl. = -53.242 deg, J2000) is +4.6 deg above the Galactic plane, and has a 95% containment radius of 7.2 arcmin (statistical errors only). The bright flat spectrum radio source, PMN J1038-5311 (RA = 10 38 40.56, Decl.
