Scientific paper

The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, has observed a short gamma-ray flare from a source positionally consistent with 3C 446 (22:25:47.2593 -04:57:01.391, J2000, Fey et al. 2004, AJ, 127, 3587) a flat spectrum radio quasar at z=1.404 (Perez, Penston & Moles 1989, MNRAS, 239, 55).
Preliminary analysis indicates that the source on 2011 October 08 was in a high state with a gamma-ray flux (E>100MeV) of (1.5 ±0.4)x10^-6 photons cm^-2 s^-1 (statistical uncertainty only).
