The Large Area Telescope (LAT), one of two instruments on the Fermi Gamma-ray Space Telescope (formerly GLAST) (launched June 11, 2008), has observed high flux from a source positionally consistent with the blazar PKS 1454-354 (R.A.: 14h57m26.7117s Dec.: -35d39m09.971, J2000, A.L. Fey et al. 2006 AJ, 132, 1944, NED B magnitude 19.5) starting on 4 September 2008. Preliminary analysis indicates that the source has brightened to a high state with a gamma-ray flux (E>100MeV) above the pre-defined LAT flaring source reporting threshold of 2x10-6 photons cm-2 s-1.
