    1329 Eliane, provisional designation 1933 FL, is a stony asteroid and slow rotator from the middle region of the asteroid belt, approximately 20 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle, on 23 March 1933.[12]

    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 has an eccentricity of 0.17 and an inclination of 14° with respect to the ecliptic.[1]

    A rotational light-curve was reevaluated by American astronomer Brian Warner at the U.S. Palmer Divide Observatory, Colorado, in 2010. The photometric observations originally taken in April 2001, revealed a very long rotation period of 106±25 hours with a brightness amplitude of 0.30 in magnitude (U=2-).[10][lower-alpha 1] According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 19.5 and 22.6 kilometers in diameter and its surface has an albedo in the range of 0.15 to 0.18.[6][4][7] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20, and calculates a diameter of 19.6 kilometers.[3]

    The minor planet was named after Éliane Bourgeois, daughter of astronomer Paul Bourgeois, professor at the discovering Royal Observatory in Uccle, Belgium, and after whom the minor planet 1543 Bourgeois is named.[2] Naming citation was published before 1977 (H 121, no M.P.C. available).[13]

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.
