	Figure 2: Maps of continuum intensity at 630.3 nm reconstructed from the SP raster scans. North is up and West to the right. The maps cover the limbside part of the penumbra in evolving AR 10930. The arrows point to the disc centre. The black and white bands indicate the areas selected for analysis.
