14833 Vilenius           Discovered 1987 Sept. 21 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Esa Vilenius (b. 1974) is a postdoctoral researcher at the Max Planck Institut f{ü}r extraterrestrische Physik in Garching, Germany. He has refined techniques for converting thermal radiometry measurements of small bodies into diameter and albedo solutions.
