13251 Viot           Discovered 1998 July 20 by the OCA-DLR Asteroid Survey at Caussols.
Hervé Viot (b. 1961) built the CCD camera used for the ODAS survey. He was also involved in many other aspects of the telescope software and hardware. His work and competence were invaluable to the success of the project. He is now involved in other projects at the Observatoire de la Côte d´Azur.
