1276 Ucclia

1276 Ucclia (prov. designation: ) is a carbonaceous Alauda asteroid from the outer region of the asteroid belt, approximately 31 km in diameter. It was discovered on 24 January 1933 by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. 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.

Orbit and classification
Ucclia is a member of the Alauda family (902), a large family of typically bright carbonaceous asteroids named after its parent body, 702 Alauda. 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. No precoveries were taken prior to its discovery.

Naming
This minor planet was named after Uccle, in honor of both, the city and the discovering observatory (H 117).

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 $30.09$ hours with a brightness variation of 0.40 in magnitude (U=3). In June 2008, a second light-curve by Slovak astronomer Adrián Galád at Modra Observatory, gave a concurring period of $30.63$ hours with an amplitude of 0.29 in magnitude (U=3-).

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. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 30.3 kilometers.
