17746 Haigha           Discovered 1998 Jan. 30 by T. Kagawa and T. Urata at the Gekko Observatory.
Haigha, pronounced to rhyme with "mayor", is an Anglo-Saxon messenger of the king in Lewis Carroll's Through the Looking Glass and what Alice found there. He lives on the Hill. The name was suggested by T. Urata.
