Hi,
The devil is in the detail, as they say.
There are definite lines visible longward of the sodium line in the first spectrum plot here and closer inspection reveals quite a few more.
With some stretching there are some 17 “real” lines just above the noise in the original image. I’m still trying to identify these. I’m confident some are W but as for the rest….
There are a few lines in this part of the spectrum in a lot of spectra I’ve captured. I’ve attributed these to weak Fe and Ca but I’ve never captured so many others. The relatively slow velocity of this meteor might be revealing some very interesting features. Work done by Jiri Borovicka on what he calls “the orange band” indicates that some of these line may actually be oxides. This will take more study but this is by far the most interesting spectrum I’ve captured.
Cheers,
Bill.
