  The AGILE Science Alert System has been developed to provide prompt
processing of science data for detection and alerts on gamma-ray galactic and
extra galactic transients, gamma-ray bursts, X-ray bursts and other transients
in the hard X-rays. The system is distributed among the AGILE Data Center (ADC)
of the Italian Space Agency (ASI), Frascati (Italy), and the AGILE Team Quick
Look sites, located at INAF/IASF Bologna and INAF/IASF Roma. We present the
Alert System architecture and performances in the first 2 years of operation of
the AGILE payload.
