Appendix A: Movie description

\end{figure} Figure A.1:

Black and white snapshot of a movie showing photospheric and chromospheric images obtained during the DOT observing run on July 4, 2006 ($\sim $07:45 UT to 10:09 UT). The movie (in color) is provided online as supplementary material to this paper. The DOT data are combined with the RHESSI light curves in the energy bands 3-6 keV (white), 6-9 keV (green) and 9-12 keV. Data gaps are due to RHESSI night times. The three microflares presented in this work peaked at $\sim $08:26 UT, $\sim $08:38 UT and $\sim $08:45 UT. The vertical white dashed line sliding through the RHESSI light curve plot marks the recording time of the DOT filtergrams and dopplergrams shown in the 4 bottom panels (G Band, Ca II H, H$\alpha $ intensities and velocities). The H$\alpha $ line of sight dopplergram is scaled to [-5, +5] km s-1 where upflows appear in blue and black and downflows in red and yellow. White contours in the dopplergrams enclose emission >70% and 90% of the maximum intensity observed in the H$\alpha $ line center. The frame boxes in each DOT image point out the location of enhanced chromospheric emission in the three microevents. The northern edge of the DOT images varies for the filters and for different times due to the speckle reconstruction process.
