- •
We have analyzed the high resolution emission spectrum of a magnitude −2.5 ± 0.5 meteor.
- •
The particle belonged to the Orionid meteoroid stream.
- •
We have identified the contributions of the atmospheric species N I, N II and O I.
- •
We have identified the contributions of meteoroid species Ti I, Cr I, Fe I, Fe II, Zr I, Pd I and W I.
- •
An upper limit of around 1500 K has been obtained for the gas temperature surrounding the meteor.
