| Abstract: |
In April 2002, Hα observations of the solar chromosphere with high spatial and spectral resolution were obtained with the Göttingen Fabry- Pérot Spectrometer mounted in the Vacuum Tower Telescope (VTT) at the Observatorio del Teide. In this work, we analyze a short time sequence of a quiet region with chains of mottles. Some physical parameters of dark mottles are determined by using Beckers’ cloud model which takes the source function, the Doppler width, and the velocity to be constant within the cloud along the line of sight. Here, we present the results of our study. |
