127196 Hanaceplechová           Discovered 2002 Apr. 16 at Ondřejov.
Hana Ceplechová (b. 1945) served as a secretary in the Interplanetary Matter Department of the Ondřejov Observatory for three decades. Her sincerity and faithfulness created a friendly work environment for the discoverers. As the wife of Zdeněk Ceplecha, she provided support for his achievements in meteor science.
