The Galactic Center is among the richest and most complex regions in the Galaxy in high-energy gamma rays, due to the density of possible sources and the brightness and structure of the diffuse gamma-ray emission originating in cosmic-ray interactions with the dense interstellar gas and intense radiation fields. Despite detection in the GeV (EGRET) and TeV range (H.E.S.S.), an accurate census of the sources of the high-energy emission in that region still eludes us. This is changing thanks to the Fermi Gamma-ray Space Telescope, which is currently surveying the sky in the energy range between 20 MeV to more than 300 GeV with unprecedented sensitivity and resolution. A source at the Galactic Center was detected with high significance after 3 months of data, and is listed in the published LAT Bright Source List (Abdo et al. 2009) as 0FGL 1746.0-2900. We report in this talk on updated characterization of this source after 11 months of data.
