VTT Echelle spectra were used to study the chromospheric evolution of active region NOAA 11126 during the period from 2010 November 18 − 22. The chromospheric fibril structure surrounding the decaying sunspots can be traced in Hαλ656.28 nm line core intensity (top) and LOS velocity (middle) maps. In addition, photospheric LOS velocities (bottom) were derived from Hinode/SP Fe i λ630.25 nm spectra. The FOV matches those of Figs. 5 and 6. Regions not covered by the spectral data are shown in medium gray. The times above the panels refers to the start of a spectral scan.
