Аннотация:Study of Benešov spectra confirms stony nature of this meteoroid. Spectroscopy is a powerful tool for study of the chemistry of impact processes in the Earth’s atmosphere. It may be used for estimation of the delivery rate of volatile elements to our planet, especially in common cases, when meteorites were not found after the impact. We plan to study CaO electronic transition, responsible for the origin of CaO orange band system in details in the future (see preliminary report of Palma et al. (2015)) in order to estimate CaO column density as a function of altitude.
