The conductivity derived from mixing length theory has often been used as an arguement that energy which one might consider "blocked" by a sunspot, is quickly distributed through out the convection zone and radiated over the thermal times scale of the convection zone. In a complimentary view, facular regions are thought of as bright regions which draw upon the thermal reserves of the entire convection zone. We examine the bright rings seen around sunspots, and by comparing to simple conductive models show that thermal perterbations in convective regions do not behave in this manner.
