AGILE is currently detecting enhanced gamma-ray emission above 100 MeV from a source which position is consistent with the blazar PKS 1510-089. (the last activity of this source was reported in ATel #9350).

Integrating from 2016-09-02 01:00 UT to 2016-09-04 01:00 UT, a preliminary maximum likelihood analysis yields a detection above 100 MeV positioned at Galactic coordinates (l,b) = (350.48, 40.76) +/- 0.7 (stat.) +/- 0.1 (syst.). The gamma-ray flux is F =(3.2 +/- 1.0) x 10E-6 ph/cm2/sec with a significance level above 5 sigma.

This measurement was obtained with AGILE observing a large portion of the sky in spinning mode. Multifrequency observations of the source are strongly encouraged.
