Abstract
The emission spectrum of a meteor was recorded by the GRASSP instrument during the observation of transient luminous events (TLEs) on 2014 October 16th. The spectroscopic signal was recorded in the wavelength range from 700 to 800nm, where the emission from atmospheric oxygen and nitrogen dominated. The good spectral resolution of the spectrum (0.24nm with 0.07nm/pixel spectral dispersion) has allowed us to determine the physical conditions in the meteor plasma, to identify several emissions from atmospheric (N I, N II, O I) and meteoroid species (Ti I, Cr I, Fe I, Fe II, Zr I, Pd I, W I) and to estimate the upper limit of the temperature of the gaseous environment surrounding the meteoroid. Images recorded for this meteor from two different sites allowed calculating its atmospheric trajectory and the orbital parameters of the progenitor meteoroid. These data revealed that the particle belonged to the Orionid meteoroid stream.
