AGILE confirms high gamma-ray state of GB6 B1310+4844

The AGILE Gamma-Ray Imaging Detector (GRID) detected significant gamma-ray emission above 100 MeV from a source consistent with the blazar GB6 B1310+4844, recently reported in a high gamma-ray state by Fermi/LAT on Nov. 18 2009 (Sokolovsky et al., ATel #2306). Integrating from 2009-11-20 17 00 UT to 2009-11-22 17 00 UT, a maximum likelihood analysis shows a detection at a significance level above 4.7 sigma, with a source flux above 100 e-8 ph/cm2/sec (E > 100 MeV), confirming the current high gamma-ray state of the source.
