24303 Michaelrice           Discovered 1999 Dec. 16 by C. W. Juels at Fountain Hills.
Michael L. Rice (b. 1943), an amateur astronomer since age 9, cofounded New Mexico Skies Observatory near Cloudcroft with his wife Lynn in 1998 after he retired from teaching finance at the University of Alaska, Fairbanks. Many have learned advanced observing and CCD imaging techniques under his excellent tutelage.
