Abstract
The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, has observed increasing gamma-ray flux from a source positionally consistent with the optically-selected and polarized (Smith et al. 2007, ApJ, 663, 118) BL Lac object SDSS J084411.67+531250.7 (also known as NVSS J084411+531250, BZB J0844+5312, and 3FGL J0843.9+5311, Acero et al. 2015, arXiv 1501.02003), with optical counterpart coordinates (J2000.0) R.A. 131.04872 deg, Dec. 53.21407 deg (Adelman-McCarthy et. al 2008, ApJS, 175, 297).
