About this image

The only decent full wavelength span Geminid spectrum from this years peak. Spectrum shows very strong neutral Mg lines and little or no ionised lines from either Mg or Ca. Interesting to compare the similarities between this spectrum and the one from 2017.

Note the narrow regular repeating lines across the spectrum (especially noticable to the left of the yellow sodium line) are processing artifacts.
