Summary:

The Large Area Telescope on-board the Fermi Gamma-ray Space Telescope has been surveying the sky above 100 MeV since August 2008. The high energy source population is dominated by the variable, flaring AGN and the steady, persistent rotation-powered pulsars. Hidden amidst these sources, Fermi has discovered and identified new transient sources from within the Milky Way. Two examples of very different systems are presented: the detection of GeV flares from the microquasar Cygnus X-3; and the unexpected discovery of a gamma-ray nova from V407 Cygni. We present multi-wavelength observations of these natural particle accelerators and place them into context with the suspected gamma-ray production and emission mechanisms.
