I have analysed my meteor spectra recorded during 2019 with a Watek 902 H2 ultimate with my Python script M_Spec (Meteor spectra analysis, new version). For each meteor a peak image of the spectrum and (if available) of the meteor viewed by a second overview camera is shown, plus some details of the processing (calibration … Continue reading Meteor spectra 2019
Meteor spectra analysis, new version
Introduction Some time ago I presented a python script for the analysis of meteor spectra. It worked as a pipeline, accepting input in a line by line form for the various parameters. It was described here (https://meteorspectroscopy.org/2018/11/18/meteor-spectraanalysed-with-python/ , referenced as m_pipe62). In the meantime it has been improved with a windows graphical user interface (GUI), … Continue reading Meteor spectra analysis, new version
Perseid meteor spectrum at OHP
Spectroscopy workshop at OHP Every year, a spectroscopy workshop is held at the site of the Observatoire de Haute Provence, where around 50 spectroscopists, beginners and experts, meet for a workshop with lectures during th day and observing during the night (www.shelyak.com/ohp-spectro-star-party-2019). I used this opportunity to record meteor spectra in a clear sky and … Continue reading Perseid meteor spectrum at OHP
Polar Lights near solar minimum
Polar Lights at Valkea Lodge, Pello, Finland, 28 February 2019 Polar lights are not related to meteors but are beautiful to view anyway. I spent a week of holidays in the Valkea Lodge in Pello, Finland, close to the swedish border and to the polar circle. As the sunspot cycle approaches the minimum, the sun … Continue reading Polar Lights near solar minimum
Meteor spectra analysed with Python
Summary This manual explains the use of a Python script for the analysis of video meteor spectra. The theory behind it has been described in (Dubs and Schlatter, 2015): meteor_spectroscopy_wgn43-4_2015.pdf). Until now, the method had been applied successfully to analyse meteor spectra obtained with high sensitive video cams such as the Watec 902 H2 ultimate … Continue reading Meteor spectra analysed with Python
M20171209 spectrum by Koji Maeda analysed
Meteor Spectrum Calibration Example Introduction Meteor spectra can give a lot of information about the meteor, such as composition and temperature. However, for amateurs the calibration of the spectra is not easy. Here a method is given for grating spectra recorded with a video camera, which produces linear spectra with constant dispersion. The method … Continue reading M20171209 spectrum by Koji Maeda analysed
