29456 Evakrchová           Discovered 1997 Sept. 24 by L. Šarounová at Ondřejov.
Since 1980 Slovak amateur astronomer Eva Krchová (b. 1953) has been a spiritus agens of amateur astronomy in Spišská Nová Ves, together with her late husband Dušan. In spite of a debilitating and incurable illness, she maintains contacts with Slovak and Czech astronomers. The name was suggested by J. Grygar.
