We shall study smooth C*×SO(n,C) actions on S2n−1, each of which is an extension of the standard U(1)×SO(n) action. We shall show such an action is characterized by a smooth R2-action on S3 and a smooth mapping of S3 onto P1(C). Moreover, we shall show there are uncountably many topologically distinct such extensions.
