As Fig. 7, but for the bright point shown in Fig. 9. The magnetograms are scaled from –70 Mx cm^-2 to +70 Mx cm^-2. The first two rows show the magnetic field evolution before the emergence of the brightening event. The white arrow points at an emerging magnetic feature which later cancels. The white circles emphasise a bipolar region created by magnetic flux emergence, while the black circles emphasise the area when and where magnetic cancellation occurs. Dotted lines outline the area where the magnetic flux lightcurve (Fig. 11) was extracted from. An animated version is available as online material, cf. Fig. A.2.
