We report the detection of a Cold Neptune m _ { planet } = 21 \pm 2 M _ { \oplus } orbiting a 0.38 M _ { \odot } 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 .
( 38 ) , 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 .
