About this image

A nice sporadic meteor spectrum. This is a type C like the super high resolution spectrum of the October 9th. The bright yellow line on the right is the unresolved sodium doublet. In the middle are the usual strong green iron lines and on the left the brighter blue line is another iron line.

This spectrum span is approx 427nm to 592nm. It's interesting to compare the two to see how the multitude of lines emerge between the usual strong lines that appear in regular, less bright spectra.
