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. 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.
The dark C-type asteroid asteroid 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.
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 4.90768 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 4.9073 hours with an amplitude of 0.29 in magnitude (U=3-).
