Query: The Fermi All-sky Variability Analysis: A list of flaring gamma-ray
  sources and the search for transients in our Galaxy   In this paper we present the Fermi All-sky Variability Analysis (FAVA), a
tool to systematically study the variability of the gamma-ray sky measured by
the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope.
For each direction on the sky, FAVA compares the number of gamma rays observed
in a given time window to the number of gamma rays expected for the average
emission detected from that direction. This method is used in weekly time
intervals to derive a list of 215 flaring gamma-ray sources. We proceed to
discuss the 27 sources found at Galactic latitudes smaller than 10 degrees and
show that, despite their low latitudes, most of them are likely of
extragalactic origin.
