A tale of two spectra

Hi,

I captured a nice spectrum a couple of night ago. When I processed the spectrum it looked kind of familiar. After having a look through my collection of spectrum I found it was indeed almost identical to a spectrum I caught of a suspected Southern Taurid fireball.

I've re-worked the 2015 spectrum to get the same span as the 2020 one.

The colourised versions show the similarities better I think....

The colourised ones are slightly misaligned but you get the idea!

Many meteors have broadly similar characteristic but these two are the closest I have seen over the years. Perhaps both are from the same parent body....

Cheers,

Bill.

Bill,

Bill,

Probably from the same parent body.

Nice spectra.

Hi Jack,

Hi Jack,

Thanks, yes they are definitely of the same "stuff". Haven't heard back from any of the NEMETODE guys if anyone else caught it. An orbit would been most interesting!

I've been having a most excellent run of results recently, long may it continue!

Cheers,

Bill.
