In our analysis we used observations of EBs obtained in the H line with the Dutch Open Telescope (DOT) and in the UV range with the TRACE 1600 Å channel. These one-hour long simultaneous sequences obtained with high temporal and spatial resolution were used to analyze the relation between the emission in the H line and at 1600 Å. The observations show fast variations of EB emission in both channels. Comparison between the observed emission in H and at 1600 Å and theoretical calculations allowed us to draw conclusions about the vertical structure of EBs.
