The "Collaborative Asteroid Lightcurve Link" assumes an albedo of 0.18 and derives a diameter of 1.99 kilometers, based on an absolute magnitude of 16.068, a figure previously obtained by the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, and later revised by Czech astronomer Petr Pravec. Between 1998 and 2016, a several rotational lightcurves of "McAuliffe" have been obtained from photometric observations taken by astronomers Petr Pravec at Ondřejov Observatory, Czech Republic, by Andreas Howell at Willowcroft Observatory, Florida, as well
