Abstract
AGILE is detecting an intense gamma-ray emission above 100 MeV from a source of Galactic coordinates (l, b) = (70.3 2.5) 1.2 deg (95% stat. c.l. and systematic error) (1-day integration). Integrating from 2010-03-24 02 24 UT to 2010-03-25 01 01 UT, a maximum likelihood analysis yields a detection at a significance level of about 5 sigma, and a flux above 250 10-8 ph/cm2/s (E > 100 MeV).
