セロ・トロロ汎米天文台
was first observed on 5 November 2012 with NOAO's 4-meter Víctor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory. Carnegie's 6.5-meter Magellan telescope at Las Campanas Observatory in Chile was used to determine its orbit and surface properties. Before being announced to the public, it was only tracked by Cerro Tololo Inter-American Observatory (807) and Las Campanas Observatory (304). It has an observation arc of about 5 years. Two precovery measurements from 22 October 2011 have been reported. A primary issue with observing it and finding precovery observations of it is that at an apparent magnitude of 23, it is too faint for most telescopes to easily observe.
