Filaments not connected with sunspots and chromospheric structure around them

The heigt stratification of the filaments (filaments in flocculi, filaments near active regions and high latitude quiet diffusion filaments) was studied. Chromospheric structure around filaments and its changing with the time was also studied. Observations were made in the center and in the wings of Hsub(α) line. The following conclusions were made. Chromosphere cells around filaments stretch our essentially. A degree of the cells stretching and its predominant direction depend on the distance from filaments This dependence is different for different types of filaments. For all types of the filaments the cells have a tendency to stretch along the axis of filaments in a neighbourhood of continuous regions and across the axis in the regions of gaps. The cells and fibrils stretched across the filament are formed near it just before disruption of filament. During filament disruption process such cells and fibrils are formed on the filament's axis of gap. Directions of fibrils and cells stretching around the filaments in flocculi coincidence approximately
