7078 Unojönsson           Discovered 1985 Oct. 17 by C.-I. Lagerkvist at Kvistaberg.
Named in honor of Uno Jönsson (b. 1937), a friend of the discoverer, to celebrate his 60th birthday. Long interested in astronomy, Jönsson has written several books for a general audience. He has also edited textbooks on astronomy, in one case with the discoverer as a contributing author.
