ah ha, I knew I had a picture of the triplet some where….
The power of spectroscopy, the same elements but on the sun (in absorption, not in emission as in a meteor spectrum!) I took this with a home made solar spectroscope, donkey’s years ago, it shows the main Mg lines plus a ton of Fe, Cr and Ti lines. These’ll be hiding in the meteor spectrum too!
Cheers,
Bill.
