AGILE is detecting increased gamma-ray emission above 100 MeV from a source positionally consistent with the FSRQ blazar CTA 102 at Galactic coordinates (l,b) = (77.29, -38.22) +/- 0.75 deg (stat. 95% c.l.) +/- 0.1 deg (syst.), (RA, Dec) = (337.82, 11.93) (J2000).
Integrating from 2017-07-05 05:46:44 UT to 2017-07-07 05:46:44 UT a preliminary maximum likelihood analysis yields a detection with a significance of 6.5 sigma and flux F(E>100 MeV) = ( 3.7 +/- 0.9) x 10^-6 ph cm^-2 s^-1.
Recent activity of CTA102 was reported in ATel #10386 by AGILE, in ATel #10330 by WEBT/GASP project and in ATel #10292 by Fermi (outside the AGILE visibility).
This measurement was obtained with AGILE observing a large portion of the sky in spinning mode.
