It was discovered by Auguste Charlois on 11 June 1891 in Nice.[3] The name was suggested to Charlois by the amateur astronomer Arthur Mee of Cardiff, Wales, to commemorate Mee's wife, Claudia.[4]
311 Claudia is one of the Koronis family of asteroids. A group of astronomers, including Lucy D'Escoffier Crespo da Silva and Richard P. Binzel, used observations made between 1998 through 2000 to determine the spin-vector alignment of these asteroids. The collaborative work resulted in the creation of 61 new individual rotation lightcurves to augment previous published observations.[5]
