  We report the discovery of Qatar-6b, a new transiting planet identified by
the Qatar Exoplanet Survey (QES). The planet orbits a relatively bright
(V=11.44), early-K main-sequence star at an orbital period of P~3.506 days. An
SED fit to available multi-band photometry, ranging from the near-UV to the
mid-IR, yields a distance of d = 101 +/- 6 pc to the system. From a global fit
to follow-up photometric and spectroscopic observations, we calculate the mass
and radius of the planet to be Mp = 0.67 +/- 0.07 Mjup and Rp = 1.06 +/- 0.07
Rjup, respectively. We use multi-color photometric light curves to show that
the transit is grazing, making Qatar-6b one of the few exoplanets known in a
grazing transit configuration. It adds to the short list of targets that offer
the best opportunity to look for additional bodies in the host planetary system
through variations in the transit impact factor and duration.
