    1276 Ucclia, provisional designation 1933 BA, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 31 kilometers in diameter. It was discovered on 24 January 1933, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.[13] Two nights later, the body was independently discovered by Richard Schorr at Bergedorf Observatory in Hamburg, Germany.[2]

    The dark C-type asteroid orbits the Sun at a distance of 2.9–3.5 AU once every 5 years and 8 months (2,070 days). Its orbit has an eccentricity of 0.09 and an inclination of 23° with respect to the ecliptic.[1]

    In 2007, a rotational light-curve was obtained by Italian and French astronomers Silvano Casulli, Federico Manzini and Pierre Antonini. It showed a well-defined rotation period of 4.90768±0.00002 hours with a brightness variation of 0.40 in magnitude (U=3).[8] In 2008, a photometric observation by Slovak astronomer Adrián Galád at Modra Observatory, gave a concurring period of 4.9073±0.0004 hours with an amplitude of 0.29 in magnitude (U=3-).[10]

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 30.1 and 40.0 kilometers in diameter and its surface has an albedo in the range of 0.05 to 0.14.[4][5][6][7] The Collaborative Asteroid Lightcurve Link (CALL) derives an albedo of 0.08 and a diameter of 30.3 kilometers.[3]

    The asteroid was named after Uccle, in honor of both, the city and the discovering observatory.[2]
