I remember this case. I have no idea where I saw it. but ATS would be my guess. Something with a balloon and logo advertising going on?

Handy, actually. Nice idea.

Even Reddit is not convinced. And that says something.. :D

Agreed about the miniature feel the picture from @Calter #53 has. Also, what is going on in the picture? Why is there a strong light-dark difference? Is this real or from any processing?

A person named sleepy_joe2024 posted a video on Reddit, featuring a disc shaped object erratically moving across the sky. The description is: I made a few screencaps The object is translucent, donut shaped. This is a key signature of out of focus point sources. The thermal camera used...

Indeed. Just plain fabricated stupid non sense. Sadly most a lot of people believe it though. Just misinformation, like the stuff Joe Rogan brings on. EDITED: Corrected above the word "most" to "a lot" because "most" is suggesting I know the numbers of statistics, which I don't.

Wasn't this that case where mr. yahweh had some help by others that used balloons? And that he was paid by the news outlet? It is very hard to find.. I cannot link to anything sensible..

Agreed with @Mendel and @JMartJr

We cannot debunk deliberate faking.

We need better or more footage of the show, I believe. We now have to work only with a few video screen grabs..

That's a neat spectrometer. Can't find any diagrams explaining the internals, but I consider that there is likely an imaging lens inside, imaging the slit (via a grating) on the detector, hence the tube. One can also make one using (curved) mirrors, making it even better at using it at lower and...

Interesting thought, @JMartJr , but it cannot explain what we see in the image of post #5.

It would be interesting to hear about how their laser systems work, indeed. The state of the art laser diodes of today can be pretty beefy, and likely put through photonic crystals or fibres, resulting in broad band high power laser light with continuous spectral wavelength selection.

I think we have come to the phase where we need to practically experiment to show it works. If only I had a few frequency modulated laser diodes at hand here..

Not hard, but I doubt the lasers were operating in that kind of configuration. The pictures above of the lasers, show they are probably large stacked laser diode banks/arrays, in combination with a beam collimator (multi lens array). Here it is more "power over control" imo, no syncing...

Incompetence or deliberately clumsy operation of the hard & software, indeed. If only they had not clicked "use auto normalize" and turned off the scale bar.. o_O

Although you are right, the image you show is not light, but a flame, which is a bunch of exited atoms. :) What also is true that light does not "collide", meaning crossing laser beams show no interaction (unless of course coherent light).

I change my position, I think now too it must be of electronic nature, rolling shutter effect and such. But it also does not look as similar as other online examples of lasers being affected by the camera/sensor. I wonder how it would only affect some of the lasers, and also only on 1 spatial...

Heavily lighted object traveling closely over a darker building.. I would expect a bit of green shine visible.

Indeed, and as a laser typically has 1-10 mrad of divergence, the size of the beam will be at least about 20 meter at 10 km. Interestingly, if you aim a laser at the moon, it will be about 770 meter wide on its surface..
