1568 Aisleen (1946 QB) is a main belt asteroid discovered on August 21, 1946 by South African astronomer Ernest L. Johnson at Johannesburg (UO). He named this object in honor of his wife.[1] This S-type asteroid is a member of the Phocaea family of minor planets that share similar orbital characteristics.[2] Based upon a light curve generated from 2001 observations, it has a rotational period of 6.68 ± 0.02 hours during which the brightness varies by 6.68 ± 0.05 in magnitude.[3]
