Abstract

Space experiments like MDI, or recently HMI on SDO, are providing unprecedented
astrometric information on the solar radius and its variation. We've made good
progress in understanding how to measure milliarcsec-scale solar changes and
tiny variations in the photometry of the solar limb. This talk will summarize
the state of our understanding of the solar limb and its implications for understanding
the solar cycle and potentially other stellar cycles.
