It was discovered on 6 September 1967, by French astronomer Guy Soulié at Bordeaux Observatory in southwestern France, who named it after the French town of Floirac.[2][27] Classification and orbitFloirac is a member of the Flora family. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,215 days). Its orbit has an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.First observed as {{mp|A914 WD}} at Simeiz Observatory in 1914, the body's observation arc begins with its 1927-identification as {{mp|1927 RB}} at Heidelberg Observatory, approximately 40 years prior to its official discovery observation at Bordeaux.[27] Physical characteristicsThis asteroid has been characterized as a stony S-type asteroid by PanSTARRS{{'}} photometric survey.[18] LightcurvesIn October 2007, a rotational lightcurve of Floirac was obtained from photometric observations by astronomer Petr Pravec and collaborating colleges. Lightcurve analysis gave a rotation period of 6.775 hours with a low brightness variation of 0.08 magnitude ({{small|U=3}}).{{efn|name=LCDB-Pravec-2007}}{{efn|name=lightcurve-plot}} An alternative period solution of 12.28 hours (Δmag 0.25) was found by French amateur astronomer Laurent Bernasconi in June 2006 ({{small|U=2}}).[11] Diameter and albedoAccording to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Floirac measures between 8.617 and 10.08 kilometers in diameter and its surface has an albedo of 0.252 and 0.302.[5][6][9][10] The Collaborative Asteroid Lightcurve Link takes an albedo of 0.2711 and a diameter of 8.73 kilometers with an absolute magnitude of 12.4, based on Petr Pravec's revised WISE-data.[3][7] NamingThis minor planet was named by the discoverer for Floirac, a French town in the Département Gironde, near Bordeaux, where the discovering observatory is located.[2] The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 2883}}).[39] Notes{{notelist|refs={{efn|name=LCDB-Pravec-2007|1=Pravec (2007) web: rotation period {{val|6.775|0.001}} hours with a brightness amplitude of {{val|0.08}} mag.
