Appendix A: Time evolution of the emerging active region

	Fig. A.1 Still image of the SDO/AIA movie at 21:30 UT on 30 May 2010: 304 Å (top left), 171 Å (top right), 193 Å (bottom left), 211 Å (bottom right). The field-of-view is 180″ × 132′′.

A movie of the evolution of the emerging active region during eight hours (17:00 UT on 30 May 2010 to 01:00 UT on 31 May 2010, 36 s time cadence) is supplied as online material.

	Fig. A.2 Still image of the SDO/HMI line-of-sight magnetic field at 21:30 UT on 30 May 2010. The field-of-view is 180″ × 180′′ centred at (–320′′, –280′′) at this particular time (reference frame for the cross-correlation).

The movie of the evolution of the magnetic field is also provided using a larger field-of-view to clearly see the supergranule pattern. The movie is for the same period of eight hours and with a cadence of 45 s.
