Oh thats genuinely realy cool.

I remember back when I lived in Berlin and studied planetary Science there. One of the Professors calculated and predicted where one of those Meteors is gonna go down. So people went there and watched and photographed it. Afterwards there was a little bit of an all hands on deck where a lot of students with different Professors went out and searched for the remains of the meteorite.

Wait a second. They predicted (before it even entered atmosphere) where it was coming down with such a precision that you could not just go out and photograph it, but even go and collect remains? I thought this was barely possible if you have a radar that is actively tracking it through the last stages of the atmosphere, while for anything still in orbit you'd be lucky to guess the correct country.

The things in earth orbit have a very small angle of entry. I'd expect that if the angle is bigger, the deflection from the atmosphere would be smaller (if it survives the hit).

I still have never seen any prediction like that which was made before the thing actually entered the atmosphere. You can see how some known remains sites were determined by clicking on them in this map: https://www.strewnify.com/map/

This is really cool.

The disclaimer on the website is weird though:

How can those be copyright protected at all given they have been taken automatically from surveillance camera without creative input from anyone?

To my (non lawyer) understanding, this would fall in the same category as CCTV footages which aren't considered worthy of copyright protection.

Any thoughts?

Looking at some of those you can understand why people claim to have seen UFOs.

Looking at them makes me think of Missile Command and I want to reach for a roller ball controller.

I wonder if the temporal noise reduction (evident in the video clips) is being applied before integrating the frames to create the thumbnails.

I use an alternative software to capture night skies and fireballs: https://github.com/aaronwmorris/indi-allsky

You can use it on Raspberry Pi, for example, with any supported camera. The software is very good, it can automatically create star trails and timelapses.
