Meteor spectra 2023

Another year has passed with many meteor spectra. Here (meteor spectra 2023) is the report of these spectra, recorded at Maienfeld during the year 2023. The spectra were recorded with a DMK 33GX249 camera from The Imaging Source (thanks to Roger Spinner for giving me this camera), equipped with a Kowa LM16HC f: 16mm F/1.4 lens and a Thorlabs 50x50mm, 600l/mm grating. All the spectra have been analysed with my Python script, based on the image transformation to an orthographic projection, freely available from Github. As last year, spectra have been analyzed by fitting synthetic spectra to to response corrected 1st order spectra when meaningful.

Meteor spectroscopy Python scripts on Github

In previous posts I have described the analysis of meteor spectra with different methods, first using conventional software then with dedicated Python scripts. Lately I have added a windows graphical user interface (GUI), which simplifies the analysis of meteor spectra (https://meteorspectroscopy.org/2020/03/27/meteor-spectra-analysis-new-version/). Now that the scripts have been tested I made them publicly available at Github (https://github.com/meteorspectroscopy).
