161962 Galchyn           Discovered 2007 Apr. 27 at the Andrushivka Observatory.
Located precisely at latitude 50\rm o north and longitude 29\rm o east, the village of Galchyn has been known since 1683. The northern part of it borders on Andrushivka, a district center in Ukraine. Because of the better seeing, the Andrushivka Observatory was set up at Galchyn.
