The HMI limb data pipeline is creating new information about the outer few hundred km of the solar atmosphere. The high signal to noise limb displacement and brightness oscillation data have yielded some surprising results. One of these is evidence of the largest rotation shear in the sun in the photosphere. This radial gradient is evidence of a stress that seems only possible from the radiated photon angular momentum. This seminar describes the limb oscillation data and the physical arguments that support a "photon brake" acting in the solar photosphere. [mehr]
