We have used a differential technique to look for the signature of g-modes at the limb of full-disk intensity images of the Sun. Our spectra show tentative evidence for a set of peaks that are equally spaced in period, as predicted by asymptotic theory. The period spacing that we find is ~ 27.5 minutes. If interpreted as ℓ = 1 g-modes, this implies To ~ 39.0 minutes.
