Spectroscopic observations of the 2011 Draconids meteor shower

International audienceSpectroscopic observations of meteors reveals the chemical composition of parent bodies and interplanetary dust. Draconids are an example of most fragile meteoroids, bringing us information about physical properties of the comet 21P/Giacobini-Zinner. During the 2011 Draconids meteor shower, airborne and ground-based meteor spectroscopic observations carried out. Here, we report on the results for spectra captured by cameras provided by the IMCCE, ESA, SETI Institute, and Ondrejov Observatory. Collected by us spectra show two dominant emissions of sodium line at 5890 Å and the magnesium line at 5180 Å. Moreover, other emision lines belong to iron and the N2 molecule.
