9117 Aude           Discovered 1997 Mar. 27 by D. Morata and S. Morata at Martigues.
Named in honor of the French "Association des Utilisateurs de Detecteurs Electroniques" (Electronic Detectors User's Association). Founded by Christian Buil and Alain Maury with the aim of assisting amateur astronomers in the use of electronic detectors, the organization is now heavily involved with the discovery and follow-up of solar-system objects and photometry of supernovae.
