AGILE confirms increased gamma-ray emission above 100 MeV from a position consistent with the flat spectrum radio quasar PKS 2023-07 (also known as 5BZQ J2025-0735, 3EG J2025-0744, 1AGLR J2027-0747 and 3FGL J2025.6-0736), recently reported in flaring activity by Fermi (Atel #8932) and previously by AGILE (Atel #8879).

Integrating from 2016-04-13 00:00 UT to 2016-04-15 04:00 UT, a preliminary maximum likelihood analysis yields a detection at 5 sigma and a flux F(E>100 MeV)=(3.2 +/- 1.1) x 10^-6 ph cm^-2 s^-1.

This measurement was obtained with AGILE observing a large portion of the sky in spinning mode. Multifrequency observations of PKS 2023-07 are strongly encouraged.
