AGILE is detecting enhanced gamma-ray emission above 100 MeV from the blazar 3C 279.
Integrating from 2018-06-03 07:56:19 UT to 2018-06-05 07:56:19 UT, a preliminary maximum likelihood analysis yields a detection at a flux F(E>100 MeV)=(7.0 +/- 1.5) x 10^-6 ph cm^-2 s^-1 and a significance greater than 7 sigma.
The enhanced flux was declared in the two Fermi-LAT notices:

https://gcn.gsfc.nasa.gov/gcn/other/1527951885_fermi.txt
and by HESS in the ATEL
#11680
This measurement was obtained with AGILE observing a large portion of the sky in spinning mode.
Multifrequency observations of the 3C 279 are strongly encouraged
