The Fermi Flare Advocate (also known as Gamma-ray Sky Watcher, FA-GSW) service provides for a quick look and review of the gamma-ray sky observed daily by the Fermi Large Area Telescope (LAT). The FA-GSW service provides alerts and communicates to the external scientific community potentially new gamma-ray sources, interesting transients and source flares. A weekly digest containing the highlights about the variable LAT gamma-ray sky at E>100 MeV is published in the web ("Fermi Sky Blog"). Other news items are occasionally posted through the Fermi multiwavelength mailing list, Astronomer's Telegrams (ATels) and Gamma-ray Coordination Network notes (GCNs). From July 2008 to January 2013 about 230 ATels and some GCNs have been published by the Fermi LAT Collaboration, more than 40 target of opportunity observing programs have been triggered by the LAT Collaboration and performed though the Swift satellite, and individual observing alerts have been addressed to ground-based Cherenkov telescopes. This is helping the Fermi mission to catch opportunities offered by the variable high-energy sky, increasing the rate of simultaneous multifrequency observations and the level of international scientific cooperation.
