Abstract
The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope (formerly GLAST, launched June 11, 2008), has observed an increasing gamma-ray flux from a source positionally consistent with B2 1520+31 (RA 15 22 09.99 , Dec +31 44 14.4 , J2000, A. J. Beasley et al. 2002, ApJS, 41, 13) since April 20, 2009.
