Title: Long Term Follow-up of Near Earth Objects
Abstract: Recently-discovered Virtual Impactors (VIs) and Potentially Hazardous Asteroids (PHAs) will be observed using the KPNO 2.1-m telescope to add astrometric observations at arcs up to 90 days from discovery. These extended arcs place strong constraints on the orbital solution and can greatly reduce the ephemeris uncertainty at the next recovery opportunity. Many recently-discovered Near Earth Objects (NEOs) will be observable in the range 21<V<23 on any night during 2014A. We will concentrate on objects where the longest arcs can be created, but we will observe other, more recently discovered NEOs as well. By creating extended arcs, we will reduce the number of the most dangerous NEOs that accumulate large errors, enabling future recovery efforts and advancing the assessment of impact risk.
