AGILE is detecting renewed and intense gamma-ray emission above 100 MeV from the flat-spectrum radio quasar CTA 102 (also known as 4C +11.69, PKS 2230+11, 5BZQ J2232+1143 and as the gamma-ray source as 3EG J2232+1147, 3FGL J2232.5+114), recently reported in flaring activity by AGILE on December 14 (ATel #9863), December 9 (Atel #9840), November 24 and 11, 2016 (ATel #9788, #9743), by Fermi-LAT on December 16 (ATel #9869), in optical/NIR/radio (ATel #9884, #9868, #9821, #9808 and #9801).
Integrating from 2016-12-27 06:43 UT to 2016-12-29 06:43 UT, a preliminary maximum likelihood analysis yields a detection at 17 sigma with a flux F(E>100 MeV)=(15.0 +/- 1.5) x 10^-6 ph cm^-2 s^-1.
The current flux is the largest ever detected by AGILE from CTA 102.
This measurement was obtained with AGILE observing a large portion of the sky in spinning mode. Multifrequency observations of CTA 102 are strongly encouraged.
