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 source positionally consistent with the optically bright BL Lac object OJ 287 (RA: 08h 54m 48.874s , Dec: +20d 06m 30.64s, J2000.0, Johnston et al. 1995, AJ, 110, 880) at z=0.306 (Falomo, Scarpa, & Bersanelli 1994, ApJS, 93, 125; Sitko & Junkkarinen 1985, PASP, 97, 1158).
