Abstract

The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-ray Space Telescope, has observed increased gamma-ray activity from the vicinity of Fermi bright source 0FGL J1641.4+3939 (Abdo, A. et al. 2009 ApJ, 700, 597). Preliminary analysis of all-sky survey data over the 36 hour period from Sep 29 (00 UT) - Sep 30 (12 UT) resulted in the detection of a source at RA = 250.661 deg, Dec = 40.1502 deg (J2000) with 95% confidence error circle= 14.0 arcmin (statistical only).
