dc.description.abstract	We use SOHO/MDI continuum images to measure the average thermal structure of bipolar spots during their initial appearance. Although the average thermal structure of penumbrae is independent of sunspot size and life span, the thermal structure of umbrae depends on the life span. This suggests that penumbrae are a shallower phenomenon and that umbrae with different life spans have different anchoring depths in the convection zone.	en
