  We report the discovery of EPIC247098361b using photometric data of the
Kepler K2 satellite coupled with ground-based spectroscopic observations.
EPIC247098361b has a mass of M$_{P}=0.397\pm 0.037$ M$_J$, a radius of
R$_{P}=1.00 \pm 0.020$ R$_J$, and a moderately low equilibrium temperature of
$T_{eq}=1030 \pm 15$ K due to its relatively large star-planet separation of
$a=0.1036$ AU. EPIC247098361b orbits its bright ($V=9.9$) late F-type host star
in an eccentric orbit ($e=0.258 \pm 0.025$) every 11.2 days, and is one of only
four well characterized warm Jupiters having hosts stars brighter than $V=10$.
We estimate a heavy element content of 20 $\pm$ 7 M$_{\oplus}$ for
EPIC247098361b, which is consistent with standard models of giant planet
formation. The bright host star of EPIC247098361b makes this system a well
suited target for detailed follow-up observations that will aid in the study of
the atmospheres and orbital evolution of giant planets at moderate separations
from their host stars.
