, a computer character code and the name of a major Japanese magazine on microcomputers. The name was proposed by Syuichi Nakano, who identified this asteroid during his stay at the Smithsonian Astrophysical Observatory; a stay which was partially funded by articles he wrote for the principal Japanese ASCII magazine. The official naming citation was published by the Minor Planet Center on 2 April 1988 ().
