KRQE-TV in Albuquerque, N.M. ran a report this past week reiterating the call, for "more money, attention, and telescopes [for] finding small asteroids," from researcher Mark Boslough, seen here with a Tunguska impact supercomputer simulation in a 2007 photo by Randy Montoya, courtesy of Sandia National Labs, which has more info, movies, and a PDF poster from that time. See also a PDF and video from Boslough's April 2009 talk at New Mexico Tech.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
