Abstract
The Large Area Telescope (LAT), one of two instruments on the Fermi Gamma-ray Space Telescope, has observed increasing gamma-ray emission from a source positionally consistent with the very-high energy peaked BL Lac object 1ES 1215+303 (also known as ON 325, Ton 605, B2 1215+30 and 3FGL J1217.8+3007, Acero et al. 2015, ApJS 218, 23) with radio coordinates (J2000) R.A. 184.467008 deg, Dec. 30.116843 deg (Petrov & amp; Taylor 2011, AJ, 142, 89). This blazar has a redshift z=0.131 (Paiano et al. 2017, ApJ, 837, 144; Bade et al. 1998, A & amp;A, 334, 459).
