1276 Ucclia (prov. designation: Шаблон:Mp) is a carbonaceous Alauda asteroid from the outer region of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 24 January 1933 by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.[1] Two nights later, the body was independently discovered by Richard Schorr at Bergedorf Observatory in Hamburg, Germany. It was named for the Belgium city of Uccle and its discovering observatory.[2]

Orbit and classification

Ucclia is a member of the Alauda family (Шаблон:Small),[3] a large family of typically bright carbonaceous asteroids named after its parent body, 702 Alauda.[4]Шаблон:Rp It orbits the Sun in the outer main-belt at a distance of 2.9–3.5 AU once every 5 years and 8 months (2,069 days). Its orbit has an eccentricity of 0.09 and an inclination of 23° with respect to the ecliptic.[5] No precoveries were taken prior to its discovery.[1]

Naming

This minor planet was named after Uccle, in honor of both, the city and the discovering observatory (Шаблон:Small).[2]

Physical characteristics

Rotation period

A rotational lightcurve of Ucclia was obtained from photometric observations by Italian and French astronomers Silvano Casulli, Federico Manzini and Pierre Antonini in March 2007. It showed a well-defined rotation period of Шаблон:Val hours with a brightness variation of 0.40 in magnitude (Шаблон:Small).[6] In June 2008, a second light-curve by Slovak astronomer Adrián Galád at Modra Observatory, gave a concurring period of Шаблон:Val hours with an amplitude of 0.29 in magnitude (Шаблон:Small).[7]

Diameter and albedo

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, Ucclia measures between 30.1 and 40.0 kilometers in diameter and its surface has an albedo between 0.05 and 0.14.[8][9][10][11] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 30.3 kilometers.[12]
