Physical parameters of the plasma tail of Rosetta target comet 67P/Churyumov-Gerasimenko Original Research Article

On the basis of photometric processing of the two large scale photographic images of comet 67P obtained in Nizhny Arkhyz with the help of the 6-BTA reflector of SAO of RAS and using the diffusion model of L. Shulman and H. Nazarchuk some physical parameters of magnetic field of the comet plasma tail (coefficients of diffusion and induction of magnetic field) were determined.
