10094 Eijikato           Discovered 1991 Feb. 20 by T. Seki at Geisei.
Eiji Kato (b. 1942), together with his wife Naomi, runs a bed and breakfast in Australia and introduces their guests to the wonders of the night sky from their in-house observatory. He also translates Comet hunter Seki's webpage into English to reach wider audiences outside Japan.
