14122 Josties           Discovered 1998 Aug. 27 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
F. Jerry Josties (b. 1937) worked at the U.S. Naval Observatory for more than four decades. He managed USNO's photographic double star program and contributed to VLBI work on the determination of polar motion, earth rotation and nutation.
