AGILE confirms the detection of enhanced gamma-ray activity from the FSRQ PKS 1313-333 (redshift z=1.210), as reported by the Fermi-LAT in ATel #8533.

Integrating from 2016-01-10 02:00 UT to 2016-01-12 02:00 UT, a maximum likelihood analysis of AGILE data yields the detection of the source at a significance level of about 5 sigma with a flux of (1.6 +/- 0.6) x 10^-6 ph/cm2/s (E > 100 MeV), in agreement with the Fermi-LAT measurement.

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