Isaak's announcement (Claverie et al. 1980) of the discovery by his group of distinct, approximately evenly spaced peaks in the power spectra of whole-disk Doppler measurements immediately raised the issue of what they imply about the structure of the solar interior. Here we report our immediate reactions, and infer that the observations seem to imply a lower sound speed, appropriately averaged throughout the interior, and probably a lower mean temperature than standard solar models predict.
