1999 (). In 2006, Warner revised his photometric data, though with no notable improvement or change for this asteroid. Diameter and albedo According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite IRAS, and the Japanese Akari satellite, Lova measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link adopts the results from IRAS, that is, a low albedo of 0.0524 and a diameter of 52.47 kilometers based on an absolute magnitude of 10.22. Alternative mean-diameter measurements published by the WISE team include (), (), () and () with corresponding albedos of (), (), () and (). Two asteroid occultations, observed on 5 April 2006 and 12 July 2007, gave a best-fit ellipse dimension of (52.0 × 52.0) and (43.3 × 64.3) kilometers, respectively, with the latter being the better rated one. These timed observations are taken when the asteroid passes in front of a distant star.
