In some cases, the expansion of a scalarﬁeld in the Bunch-Davies vacuum includes supercurvature modes, as shown by Sasaki, Tanaka andYamamoto. We express the normalizable vacuum supercurvature modes for a massless scalar ﬁeldin terms of the basis modes for the spatially-ﬂat slicing of de Sitter space.Preprint UIUC-98/2; HUTP-98/A010; gr-qc/9803073I.
