The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, has observed increasing flux from a new gamma-ray source positionally consistent with the flat spectrum radio quasar PMN J2012-1646 (RA: 20:12:30.150 Dec: -16:46:50.60, J2000; Healey et al. 2007, ApJS, 171, 61) with a 95% containment radius of 0.22 deg. The daily averaged gamma ray flux was (0.7+/-0.2) 10^-6 photons cm^-2 s^-1 in the 100 MeV - 300 GeV energy range on December 28, 2012. All flux and position errors are statistical errors only. This source is not included in any Fermi LAT catalog.

Because Fermi operates in an all-sky scanning mode, regular gamma-ray monitoring of this source will continue. Multiwavelength observations of this source are strongly encouraged. The Fermi LAT contact person is Roopesh Ojha (e-mail: Roopesh.Ojha@gmail.com).

The Fermi LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.
