The latest higher sensitivity WATEC cameras (the 910's) have began to show meteors in a slightly new way.
Video observing shows a wide variety of effects, some meteors seem to flash into then out of existence whereas other are much slower. Recently, though, I've started to notice some that positively ooze out of existance. I'm sure these have always been there but the better performance of the new cameras gives a much better view of the effect.
I've put a recent capture on youtube at https://www.youtube.com/watch?v=-thc7_H4F6c
The meteor can seen to elongate and fade away. I've not processed it yet, but last night I captured another one that was so slow the video capture software stopped recording before it finally disappeared from view when it fell below the threshold of the motion filter.
I imagine there is a confluence of material properties and orbital parameters that causes the effect on a propotion of meteors. There is also the effect of double brightness peaking meteors. The video shows this effect too by co-incidence. This has been the subject of previous professional research but that was on a relatively small sample. I've already received information from other video observers who have kindly sent me some of their images. Definitely another interesting feature to explore.
Even after a decade of video observing there's still new things to see!
