AGILE detection of a possible rebrightening of the gamma-ray source AGL J2021+4032 in the Cygnus Region

During the current AGILE pointing centered near the Cygnus Region the Gamma-Ray Imaging Detector (GRID) has detected a source positionally consistent with the gamma-ray source previously reported in ATel#1585. Integrating from 2008-11-16 14 33 UT to 2008-11-17 14 22 UT, a preliminary maximum likelihood analysis shows a detection at a significance level near 5 sigma, with a source flux more than two standard deviations above the mean flux reported in ATel#1585.
