24411 Janches           Discovered 2000 Jan. 7 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Diego Janches (b. 1967) is a space weather scientist at the Goddard Space Flight Center. He uses radar observations of microgram-size meteors to refine models for their mass influx, and has developed a meteor radar system in southern Argentina covering unsurveyed southern sky.
