Query: MOA-2013-BLG-220Lb: Massive Planetary Companion to Galactic-Disk Host   We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass
ratio $q=3.01\pm 0.02\times 10^{-3}$ relative to its host. The proper motion,
$\mu=12.5\pm 1\, {\rm mas}\,{\rm yr}^{-1}$, is one of the highest for
microlensing planets yet discovered, implying that it will be possible to
separately resolve the host within $\sim 7$ years. Two separate lines of
evidence imply that the planet and host are in the Galactic disk. The planet
could have been detected and characterized purely with follow-up data, which
has important implications for microlensing surveys, both current and into the
LSST era.
