Rebrightening of the variable AGILE source in the Cygnus region

While pointing at the Cygnus region, AGILE detected renewed gamma- ray emission from the transient gamma-ray source previously reported in ATel #1492, beginning on 2008-05-22 UT. A preliminary maximum likelihood analysis of the AGILE-GRID (Gamma-Ray Imaging Detector) data obtained between 2008-05-22 06 00 UT and 2008-05-27 06 00 UT for photon energies above 100 MeV results in a detection significance of about 6 sigma, with a source flux in excess of 100e-8 ph/cm2/s at energies above 100 MeV.
