The GRID detector onboard the AGILE satellite is detecting gamma-ray
activity from the blazar 4C29.45 (z = 0.72475, Ahn et al., ApJS,
2012, also known as 5BZQ J1159+2914). Integrating from 2023-01-08 UT 00:00:00
to 2023-01-10 UT 00:00:00, a preliminary multi-source likelihood analysis yields a
detection with a significance of 5.4 sigma, and a gamma-ray flux
F(>100 MeV) = (3.8 +/- 1.1) x 10^-6 photons/cm^2/s.
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.
