The remarkable spectrum of post #35 has become even more remarkable after attending a presentation by the meteor spectroscopy expert Jiri Borovicka at the International Meteor Conference in the Netherlands a few days ago. (A wonderful event I can recommend!)

The reason that I couldn’t identify many of the lines is that they are not atomic lines. Atomic lines are the only ones I have in the software databases I use but the lines visible are actually compounds! They are probably mostly emissions from oxides such as aluminum oxide. This makes it an even more unusal meteor.

Good stuff!
