Line-of-sight magnetic field maps of the upper right quarter of a sunspot penumbra, including its surrounding moat region, observed by SOT-SP in Normal Map mode, thus having a pixel size of |${0{^{\prime \prime }_{.}}16}$|⁠. The evolution of eight moving magnetic features are outlined by circles, each in a different color: red (panels a–c), yellow (panels a–e), orange (panels a–f), violet (panels c–f), green (panels a–f), blue (panels a–c), cyan (panels a–f), and ivory (panels a–f). The SP data used in this figure were inverted at the Community Spectropolarimetric Analysis Center 〈http://www2.hao.ucar.edu/csac〉. (Color online)
