38246 Palupín           Discovered 1999 Aug. 14 by J. Ticha and M. Tichy at Klet.
Palupín is a small pleasant village with a manor-house in the Czech-Moravian Highlands that was first mentioned in 1368. St. Wenceslaus church was built by a local landlord in 1617. The family roots of co-discoverer J. Ticha (nee Peltan) lie in this village.
