Record breaking meteor spectrum

[Bill Ward]

Hi all,
After a relatively quiet spell, there was a spectacular mag -9 fireball over central Scotland late on the 9th October
Due to the fall of the fireball and it’s brightness I captured an extremely high resolution 2nd order spectrum.
This is, by far, the most detailed video meteor spectrum ever captured.
Initial inspection reveals it to be a Type C with a very strong Sodium emission and the rest (mostly?) iron lines.
There are well over 145 lines in the 2nd order spectrum. Untangling the orders was very difficult and I’m not 100% certain that I’ve unpicked them all…
The spectrum plot is instrument corrected and the synthetic coloured spectrum is just remarkable!
Cheers,
Bill.
