AGILE is detecting increased gamma-ray emission above 100 MeV from a source positionally consistent with the flat spectrum radio quasar PKS 0502+049.

Integrating from 2014-09-08 03:00 UT to 2014-09-10 03:00 UT, a preliminary maximum likelihood analysis yields a detection above 100 MeV positioned at Galactic coordinates (l,b) = (195.47, -20.81) +/- 0.6 (stat.) +/- 0.1 (syst.). The gamma-ray flux is F =(3.9 +/- 1.0) x 10E-6 ph/cm2/sec with a significance level above 6.0 sigma.

Flaring activity from this source has been recently reported by Fermi-LAT and Swift in ATel #6425.

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