311 Claudia is a typical Main belt asteroid.

It was discovered by Auguste Charlois on June 11, 1891 in Nice. The origin of the name of this asteroid remains unknown, as do many other of his discoveries. [ Schmadel Lutz D. Dictionary of Minor Planet Names (fifth edition), Springer, 2003. ISBN-10: 3540002383.]

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. [Slivan, S. M., Binzel, R. P., Crespo da Silva, L. D., Kaasalainen, M., Lyndaker, M. M., Krco, M.: “Spin vectors in the Koronis family: comprehensive results from two independent analyses of 213 rotation lightcurves,”Icarus, 162, 2003, pp. 285-307.]
