  Analysis of data from the Fermi Large Area Telescope (LAT) in the region of
the supernova remnant G78.2+2.1 reveals an excess at the position of the TeV
source VER J2019+407. The GeV source is extended with a hard spectrum and it is
likely the counterpart of the TeV source. The spectrum of the LAT emission
connects smoothly with that of VER J2019+407, and the overall GeV--TeV spectrum
is best described by a broken power-law with indices 1.8 and 2.5 below and
above a break energy of 71 GeV. Several scenarios are considered to explain the
nature of this unidentified gamma ray source.
