  We present results from our observing campaign of Comet 209P/LINEAR during
its exceptionally close approach to Earth during May of 2014, the third
smallest perigee of any comet in two centuries. These circumstances permitted
us to pursue several studies of this intrinsically faint object, including
measurements of gas and dust production rates, searching for coma morphology,
and direct detection of the nucleus to measure its properties. Indeed, we
successfully measured the lowest water production rates of an intact comet in
over 35 years and a corresponding smallest active area, ~0.007 km^2. When
combined with the nucleus size found from radar (Howell et al. 2014), this also
yields the smallest active fraction for any comet, ~0.024%. In all, this
strongly suggests that 209P/LINEAR is on its way to becoming an inert object.
The nucleus was detected but could not easily be disentangled from the inner
coma due to seeing variations and changing spatial scales. Even so, we were
able to measure a double-peaked lightcurve consistent with the shorter of two
viable rotational periods found by Hergenrother (2014). Radial profiles of the
dust coma are quite steep, similar to that observed for some other very anemic
comets and suggestive that vaporizing icy grains are present.
