(19315) Aizunisshinkan Main-belt Asteroid
Discovered on 7 November 1996 by Endate, K., Watanabe, K. at Kitami.
During the Edo period in Japan, Nisshinkan (1803–1868) was a school opened to educate the children of Aizu feudal lords in the civil and military arts. There were up to 250 similar schools throughout Japan, but only a few of them had an observatory. Today, only the ruins of the Nisshinkan observatory remain and are open to the public.Naming citation (WGSBN Bull. 3, #8, 11), IAU / Minor Planet Center, via NASA/JPL
