Temporal evolution of the fitted spectral profiles (normalized to the local continuum intensity I_lc) for the red component of the He I triplet. The rainbow-colored bar indicates the elapsed time after the start of the one-hour time series. The spectra were taken at a strong downflow kernel marked by a blue filled circle in the second panel of Fig. 3. These profiles are an average of all fitted spectral profiles within the blue patch and do not refer to individual fits. The spectra were slightly smoothed to avoid a cluttered display.
