  We report the detection of a Cold Neptune m_planet=21+/-2MEarth orbiting a
0.38MSol M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a
campaign combining ground-based and Spitzer observations to measure the
Galactic distribution of planets. This is the first time that the complex
real-time protocols described by Yee et al. (2015), which aim to maximize
planet sensitivity while maintaining sample integrity, have been carried out in
practice. Multiple survey and follow-up teams successfully combined their
efforts within the framework of these protocols to detect this planet. This is
the second planet in the Spitzer Galactic distribution sample. Both are in the
near-to-mid disk and clearly not in the Galactic bulge.
