AGILE is detecting enhanced gamma-ray activity above 100 MeV from the blazar PKS 0208-512 (also known as 5BZU J0210-5101). Integrating from 2019-12-14 UT 08:00:00 until 2019-12-16 08:00:00, a preliminary multi-source maximum likelihood analysis yields a detection above 6 sigma and a flux F(>100 MeV) = (2.7 +/- 0.8) x 10^-6 photons/cm^2/s.
Recently, intense gamma-ray activity from this source was reported by Fermi-LAT in the ATel #13320.
The AGILE-GRID detection was obtained while AGILE is observing in spinning mode, surveying a large fraction of the sky each day. The source can be monitored with the public mobile application "AGILEScience" developed by the AGILE Team, available for both Android and iOS devices.
Multifrequency observations of PKS 0208-512 are strongly encouraged.
