14032 Mego           Discovered 1994 Dec. 4 by M. Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory.
Princess Mego (1568-1653) was the wife of Datemasamune, a feudal lord in the Sendai area. After marriage she took the name Yotuko-in. Her birthplace in Miharu, Fukushima prefecture, is famous for a very old cherry tree, Takisakura. A seedling planted near the Sendai Observatory is known as the "Princess Mego Cherry Tree".
