As promised… Captured another “slow fade” meteor and also another bright meteor to compare it to.
These were both caught with the same camera system on the same calendar day. (One was from the morning and the other early evening.)

Comparison meteor light curve.
By using the slice function in IRIS smoothed curves were plotted showing the light curves.
Axes are simply x:pixel and y:rel intensity
It can be seen the onset is very similar, then the mechanics come into play. The ablation characteristics change and the meteors “burn out” quite differently.
The graphs show the more rapid decline of the comparison and the slower decline of the fading meteor, nice to see a measureable difference.
