Appendix B: Online movie

The movie Bmovie.gif shows the evolution of the LOS magnetic flux derived from COG in an area surrounding the pore. A subsonic filter was applied to the sequence. To reduce aliasing effects, the FOV was apodized and reduced to 33.3′′ × 33.3′′. The magnetic flux is clipped at −200 and 100 G to highlight the formation and evolution of the investigated MMFs. A still frame from the movie, acquired at 17:21:29 UT, is shown in Fig. B.1.
