15403 Merignac           Discovered 1997 Nov. 9 by L. Šarounová at Ondřejov.
The city of Merignac in southwestern France has expanded in recent years because of several aeronautics and space industries. However, the city also has a pleasant living environment, preserving trees and vegetation. The name was suggested by J. Montanné.
