167208 Lelekovice           Discovered 2003 Oct. 17 by P. Kušnirák and K. Hornoch at Ondřejov.
The picturesque village of Lelekovice, near Brno, is the birthplace of the second discoverer, who has also made observations of comets and supernovae for more than two decades from his private observatory there. The naming of this minor planet commemorates the 720th anniversary of the founding of the village.
