Abstract
AGILE is detecting enhanced gamma-ray emission from a source positionally consistent with the microquasar Cygnus X-3. Integrating during the period 2011-05-28 07 58 37 UT to 2011-05-29 06 02 51 UT (MJD=55709.33-55710.25) the AGILE-GRID detected gamma-ray emission above 100 MeV from a source at Galactic coordinates (l, b) = (79.8, 0.3) 0.8 (stat.) 0.1 (syst.) deg, and flux F > 300 x 10-8 photons/cm2/s above 100 MeV (1-day multi-source-analysis significance in spinning mode ~4 sigma).
