The Fermi Flare Advocate (also known as Gamma-ray Sky Watcher, FA-GSW)
service provides for a daily quicklook analysis and review of the high-energy
gamma-ray sky seen by the Fermi Gamma-ray Space Telescope. The duty offers
alerts for potentially new gamma-ray sources, interesting transients and
relevant flares. A public weekly digest containing the main highlights about
the GeV gamma-ray sky is published in the web-based Fermi Sky Blog. During the
first 3 years of all-sky survey, more than 150 Astronomical Telegrams, several
alerts to the TeV Cherenkov telescopes, and targets of opportunity to Swift and
other observatories have been realized. This increased the rate of simultaneous
multi-frequency observing campaigns and the level of international cooperation.
Many gamma-ray flares from blazars (like extraordinary outbursts of 3C 454.3,
intense flares of PKS 1510-089, 4C 21.35, PKS 1830-211, AO 0235+164, PKS
1502+106, 3C 279, 3C 273, PKS 1622-253), short/long flux duty cycles,
unidentified transients near the Galactic plane (like J0910-5041, J0109+6134,
the Galactic center region), flares associated to Galactic sources (like the
Crab nebula, the nova V407 Cyg, the microquasar Cyg X-3), emission of the quiet
and active sun, were observed by Fermi and communicated by FA-GSWs.
