(10058) Ikwilliamson Main-belt Asteroid
Discovered on 25 February 1988 by R. H. McNaught at Siding Spring.
Isabel K. Williamson (1908–2000) won the Royal Astronomical Society of Canada's Chant Medal in 1948. Her observations of aurora and meteors were highly regarded by professional scientists. The first Messier Club was the result of her efforts. RASC Montreal Centre's former observatory and current library were named in her honor.Naming citation (WGSBN Bull. 1, #8, 5), IAU / Minor Planet Center, via NASA/JPL
