The sun's oscillations carry clues to its interior, and astronomers have been watching them avidly with a network of telescopes called the Global Oscillation Network Group and a space-based observatory called SOHO (Science, 31 May 1996, p. 1264). But so far, the sun's deepest notes--slow pulsations that stir its very core--have eluded them. At a workshop early this month in Boston, researchers discussed new strategies for identifying these deep undulations and weighed one claim of a candidate detection.
