Abstract

Our preliminary results indicate that sunspots lead associated plages by an amount that is directly proportional to the plage area. Our next step will be to digitize a series of spectroheliograms to better calibrate this relation. We also plan to examine other solar data sets as proxies for spot and plage signals to better determine whether a phase lag is measureable from stellar-like observations of the Sun, and thus, whether suitable observations of solar-type stars could yield information concerning areas of stellar active regions.
