9667 Amastrinc           Discovered 1997 Apr. 29 by Spacewatch at Kitt Peak.
Amateur Astronomers, Inc., was founded in 1949 and incorporated in 1956. After 1961 the AAI moved to Union College, Cranford, New Jersey, where it built and instrumented the fine William Miller Sperry Observatory and is involved in research and education. The name was suggested by J. Montani.
