Scientific paper

The Large Area Telescope (LAT), on board the Fermi Gamma-ray Space Telescope, has observed a gamma-ray flare from a source positionally consistent with the flat spectrum radio source PMN J1913-3630, also known as VCS4 J1913-3630 (RA = 19:13:20.89, Dec = -36:30:19.4, J2000; L. Petrov et al. 2006 AJ 131, 1872). The source has no known redshift.
Preliminary analysis indicates that the source on October 21, 2010 showed a bright gamma-ray outburst with a daily flux (E>100MeV) of (1.3 +/- 0.3) x 10^-6 ph cm^-2 s^-1 and a peak of (2.3 +/- 0.7) x 10^-6 ph cm^-2 s^-1 (errors are statistical only) observed between 18:00 and 22:00 UT.
