Robert Stephens (b. 1955) is a Californian amateur astronomer who has
determined some 30 sets of minor-planet lightcurve parameters since becoming
active in the field in 1999. His high-quality work and generosity in sharing
his time and knowledge within the amateur community have set a standard for
others to follow.
