Abstract

Abstract: We demonstrated the capability of the updated Canary Island Long Baseline Observatory (CILBO) meteor detection system to measure relative elements intensities of meteors. Meteor spectra provide valuable information on the chemical properties of individual meteoroids. In some cases, this may be the only information on the chemical composition of the parent bodies, and on transforming processes that occur during the meteoroid's journey from its source to Earth. The CILBO spectroscopic program has been created with the intention of carrying out regular systematic spectroscopic observations. At the same time, the meteoroid trajectory and pre-atmospheric orbit are independently measured from data collected by the other cameras in the network. We presented the meteor spectroscopy pipeline developed by the Meteor Research Group of the European Space Agency, and it's application to the spectroscopic survey of Geminid meteor shower observed by CILBO. Highlights: We demonstrated the capability of the ESA/CILBO meteor detection system. We analysed a sample of meteor spectra collected in December 2013 and 2015. In the sample of the Geminids collected by CILBO we see a variation in the level of sodium.
