 Lightcurve analysis gave a well-defined rotation period of hours with a brightness variation of magnitude ().The result confirms and refines previous observations by French amateur astronomer René Roy in February 2003, which gave a period of hours with an amplitude of magnitude (), by Jean-Gabriel Bosch at the French Collonges Observatory in February 2006, which gave an identical period of hours with an amplitude of magnitude (), by James W. Brinsfield at the Via Capote Observatory in Australia in November 2008, which gave the first secured period of hours with an amplitude of magnitude ().According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE) and the Infrared Astronomical Satellite IRAS, "Baumeia" measures () and () kilometers in diameter and its surface has an albedo of () and (), respectively.
