Title: Determining Orbits and Sizes of Near-Earth Objects Discovered by NEOWISE

Abstract: Near-Earth Objects (NEOs) are asteroids or comets with perihelia $< 1.3$ AU. NEOs provide an opportunity to investigate the smallest asteroids but also may pose a serious threat. Discovering NEOs and determining their orbits and sizes is essential to assessing the risk of an impact or explosion. NEO studies also enable detailed investigations of inner solar system objects and the processes that govern their physical and dynamical evolution. The NEOWISE space mission is currently discovering NEOs in the infrared, so that when paired with optical follow-up from the ground, precise orbits, albedos, and thermal inertia values can be calculated. The only facilities that have secured NEO follow-up time are $1-2$ meter class telescopes, so these are sometimes too small to reach our faint and/or low-albedo targets. We propose to continue our successful program from 2014B, 2015A, 2016A, and 2016B by requesting a small amount of ToO time on Blanco/DECam to fill in these significant gaps in coverage that regular follow-up observers cannot fill. Without these observations, faint and/or dark NEOWISE NEO candidates will be lost.
