Title: Recovery of 2008 UB7, one of the most dangerous known NEOs

Abstract: Among the observational activities dedicated to NEOs, one of the most important and often neglected components is astrometric follow-up. Among the $sim 500$ known NEOs with non-zero impact probability in the next century, even some of the highest-rated ones have very poorly known orbits, resulting from an insufficient observational coverage during their discovery apparition. For these objects it is essential to take advantage of all available opportunities to recover the object and secure the predictability of their future motion. We propose to use a small amount of telescope time with the CTIO DECam imager to obtain recovery observations of one of the most dangerous known NEOs, designated 2008 UB7, during a unique observational geometry that will happen for just a few days in early June 2017. If successful, the observations will entirely clarify the future impact threat from this object; in the unlikely event that any future collision is confirmed, they will make possible to collect physical observations essential to properly estimate the actual damage from the collision.
