1329 Eliane, provisional designation 1933 FL, is a stony asteroid and slow rotator from the middle region of the asteroid belt, about 20 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle, on 23 March 1933.[10]

The S-type asteroid orbits the Sun at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,546 days). Its orbit is tilted by 14 degrees to the plane of the ecliptic and shows an eccentricity of 0.17.[1] Reevaluated data from photometric light-curve observations at the U.S. Palmer Divide Observatory in Colorado (also see § External links) revealed a notably long rotation period of 106 hours.[7][lower-alpha 1] According to the surveys carried out by the Japanese Akari satellite and the U.S. Wide-field Infrared Survey Explorer and its NEOWISE mission, the asteroid's surface has an albedo of 0.15 and 0.18, respectively, while the Collaborative Asteroid Lightcurve Link (CALL) assumes a value of 0.20, which is a somewhat more typical value for stony asteroids.[3][4][5][6]

The minor planet was named in honor of Éliane Bourgeois, daughter of astronomer Paul Bourgeois, professor at the Royal Observatory in Uccle, Belgium, and after whom the minor planet 1543 Bourgeois is named.[2]

  1. ↑ Note to Warner's Revised rotation period: "Updated results are given for six asteroids previously reported from the Palmer Divide Observatory. The original images were remeasured to obtain new data sets using the latest version of MPO Canopus photometry software, analysis tools, and revised techniques for linking multiple observing runs covering several days to several weeks. Results that were previously not reported or had significantly different periods and/or amplitudes were found for 1329 Eliane, 1582 Martir, 2023 Asaph, 8041 Masumoto, (26853) 1992 UQ2, and (52387) 1993 OM7. This is the second in a series of papers that examines results obtained during the initial years of the asteroid lightcurve program at PDO." Upon Further Review: II.
