300E-319-Lost and Found
When asteroid hunters follow an object in the night sky for a few hours or a couple of days they are only able to observe a snippet or tracklet of the object's hundreds to thousands of days long path around the Sun. If we only have a short sample of an orbit we loose precision to locate the object as the length of time since the last observation increases. It is thus possible to lose the knowledge of where to find a particular asteroid.
