17893 Arlot           Discovered 1999 Mar. 17 by the OCA-DLR Asteroid Survey at Caussols.
Jean-Eudes Arlot (b. 1948) is the current director of the Institut de Mécanique Céleste in Paris and chair of the IAU Commission 20 working group on satellites. He has worked on a theory of the motions of Jupiter's Galilean satellites and organised international campaigns to observe the mutual phenomena of these bodies.
