    13390 Bouška, provisional designation 1999 FQ3, is a stony Eunomia asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered by Czech astronomers Petr Pravec and Marek Wolf at Ondřejov Observatory in the Czech Republic on 18 March 1999.[8]

    The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.1–3.0 AU once every 4 years and 2 months (1,516 days). Its orbit has an eccentricity of 0.18 and an inclination of 13° with respect to the ecliptic.[1]

    In 2012, a photometric light-curve analysis at the U.S. Palomar Transient Factory in California gave a rotation period of 7.7572±0.0027 hours with a brightness amplitude of 0.30 in magnitude (U=2).[6]

    According to the surveys carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 7.5 and 7.0 kilometers in diameter and its surface has an albedo of 0.26 and 0.27, respectively.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21 and calculates a somewhat smaller diameter of 6.5 kilometers.[3]

    The minor planet is named in honor of astronomer and retired professor at Charles University, Jiří Bouška (b. 1925), whose research concentrated on the material found between the planets of the Solar System. He has been a teacher of several generations of Czech astronomers, including one of the discoverers. For decades he has also been the editor of the Czech Astronomical Yearbook and the popular astronomy journal Ríše hvězd (The Realm of Stars), after which the minor planet 4090 Říšehvězd is named.[2]
