Abstract

The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope discovered a rapid gamma-ray flare 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, -- redshift z=0.306, Falomo, Scarpa, & Bersanelli 1994, ApJS, 93, 125; Sitko & Junkkarinen 1985, PASP, 97, 1158).
