Abstract
AGILE is detecting intense gamma-ray emission above 100 MeV from a source positionally consistent with BL Lacertae, at Galactic coordinates (l, b) = (93.3, -10.22) 0.8 (stat.) 0.1 (syst.) deg. Integrating from 2011-05-27 11 57 31 UT to 2011-05-29 11 30 51 UT (MJD 55708.5-55709.5), a maximum likelihood analysis yields a detection at a significance level larger than 5 sigma and a flux F = (3.9 1.2) x 10-6 ph/cm2/s (E > 100 MeV).
