Naming Citation:   JohnPercy = (32208) = 2000 OR7
John Percy Minor White and Myke Collins discovered this asteroid July 27, 2000, just a couple degrees from the planet Neptune.  At discovery it was very close to 2000 OQ7 and later we would see a strong orbital resemblance.

We were able to establish a 60-day opposition arc which allowed us to make pre-recoveries from 1992, 1996 and 1999.  This allowed us to pick up the asteroid early in the 2001 opposition and the surveys provided additional coverage during the 2001 opposition.  These observations provided strong enough orbital elements to permit the asteroid to be numbered late in 2001.

At 9 km in diameter, this is the largest MBO we have discovered.  It also has an unusually circular orbit, which keeps its visual magnitude fairly constant at oppositions.  Its eccentricity is only 0.01.

The official citation reads:
  "Dr. John Percy (born 1941. Windsor, UK) is a professor of astronomy and astrophysics at the University of Toronto.  He has written over 400 scientific papers, articles and books on variable stars and astronomy education.  His organizational affiliations span the globe, and his many awards show his dedicated support to astronomy education.  He is the husband of Dr. Maire E. Percy."  

The name JohnPercy was proposed by Peter Broughton (RASC).  Peter was a contemporary of Dr. John Percy at the University of Toronto as well as a friend of his family.  Peter taught Mathematics and Physics in Toronto for 33 years.  His interest in astronomy has centered on its historical development.
