In 1989, Rhaly determined the spectrum of Rhaly operator R-a regarded as an operator on the Hilbert space I-2 normed by parallel to x parallel to = (Sigma(n) \ x(n) \(2))(1/2). It is the purpose of this paper to determine the spectrum of Rhaly operator R-a as an operator on the spaces bupsilon(0), and b(upsilon).
