Scientific paper

The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, has observed an increasing gamma-ray flux from a new source positionally consistent with PKS 1915-458 (19:19:16.66 -45:43:38.4, J2000) a flat spectrum radio quasar at z=2.47 (Jackson et al. 2002, A&A, 386, 97). The redshift is unusually high for a flaring LAT blazar, however not unprecedented (ATEL #2217).
