Abstract
The properties of the light scattering on a column-like bullet and droxtal of cirrus clouds oriented preferably in a horizontal plane have been calculated in the geometrical optics approximation. The shape parameters of crystals F and the flutter are assumed to be equal to 10 and 5 degrees respectively. The Parry and 3D orientations of crystals in space have been analyzed. Based on the results, the tabular information of the distribution of the scattered light among the brightest halo has been represented. The results have been compared with scattering on the hexagonal column.
